Gary,

Thanks for the response.  we raise events as follows:
   Private Shared _defaultLevel As EventLevel = EventLevel.Error

   Public Shared Sub Publish(ByVal ex As Exception, ByVal message As
String)
       Dim messageEvent As New ErrorMessageEvent
       Dim detail As String = ""

       If Not ex Is Nothing Then
           detail = FormatException(ex) & NewLine & message
       Else
           detail = "Missing exception." & NewLine & message
       End If
       messageEvent.Message = detail
       messageEvent.EventPublishLogLevel = CInt(DefaultLogLevel)
       EventSource.Application.Raise(messageEvent)
end sub

We are using .NET v1.1, running on Windows2003, using:
Microsoft.ApplicationBlocks.Common.dll
Microsoft.ApplicationBlocks.Logging.EventSinks.dll
Microsoft.ApplicationBlocks.Logging.Schema.dll
and of course the EIF.

We did not modify the code in these applications.  We use config
information of:  
WEB.Config:
        <section name="eventFormatterSettings"
type="Microsoft.ApplicationBlocks.Logging.EventSinks.FormatterConfigHandler,
Microsoft.ApplicationBlocks.Logging.EventSinks, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=3223a35ad8aa5af3" />
<appsettings>
    <add key="applicationLogLevel" value="error" />
</appsettings>

    <eventFormatterSettings>
            <!-- This formatter is used by the Metering
Publisher to
       format the information that goes into the metering event
before
       raising it to the event sink -->
            <formatterInfo name="meteringFormatXslt"
type="Microsoft.ApplicationBlocks.Logging.EventSinks.XsltEventFormatter,
Microsoft.ApplicationBlocks.Logging.EventSinks, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=3223a35ad8aa5af3"

fullyQualifiedDefaultXsltPath="eventlogmeteringtransform_plaintext.xslt"
/>
            <!-- This formatter is used by the EIF -->
            <formatterInfo name="logSinkXslt"
type="Microsoft.ApplicationBlocks.Logging.EventSinks.XsltEventFormatter,
Microsoft.ApplicationBlocks.Logging.EventSinks, Version=1.0.0.0,

fullyQualifiedDefaultXsltPath="eventlogtransform.xslt" />
            <formatterInfo name="basiclogSinkXslt"

            <formatterInfo name="meteringlogSinkXslt"

            <formatterInfo name="msmqSinkXslt"

            <formatterInfo name="sqlSinkXslt"

fullyQualifiedDefaultXsltPath="c:\Projects\GMIStandard\SharedFiles\StyleSheets\eventsqltransform.xslt"
/>
    </eventFormatterSettings>

Finally, we also have a Enterprise Config with:
 <filters>
   <filter name="defaultSoftwareElementFilter"
        description="A default filter for the Software Element
event sources.">
            <eventCategoryRef name="All Events">
                <eventSinkRef name="logSink" />
                <eventSinkRef name="sqlSink" />
            </eventCategoryRef>
        </filter>
 </filters>
   <eventSink name="logSink" description="Outputs events to the
Windows Event Log."
type="Microsoft.EnterpriseInstrumentation.EventSinks.LogEventSink">
     <parameter name="entryTypeFieldName" value="EventLogEntryTypeID"
/>
     <parameter name="defaultEntryType" value="Information" />
     <parameter name="machineName" value="." />
   </eventSink>
   <eventSink name="sqlSink" description="Outputs events to the Sql
Server flexible Log."
type="Microsoft.ApplicationBlocks.Logging.EventSinks.SqlServerEventSink,
Microsoft.ApplicationBlocks.Logging.EventSinks, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=3223a35ad8aa5af3">
        <parameter name="connectionString"
value="Password=VMKDSIAGFIO887;Persist Security Info=True;User
ID=MWEB033;Initial Catalog=DWEB_ERR;Data Source=JFBDBSCT1-V1\T1" />
        <parameter name="numberOfRetries" value="0" />
        <parameter name="formatterName" value="sqlSinkXslt" />
   </eventSink>

I hope some of this helps.

Thanks,
Patrick
