You nailed it - cryptic but powerful.  I couldn't figure out how to get it to split the Message field by CrLf, so I had to hack it a little bit, using the colon as my delimiter and cutting out the subsequent field name.  Should be okay so long as no paths have the word Handle ID in them.
 
For those who are interested, here's the syntax I used from a command prompt.  With a little effort this can be turned into a DHTML page (see the Samples directory after you've installed LogParser).
logparser "select distinct eventid,
TO_STRING(TimeGenerated, 'dddd, MMMM d, yyyy') AS LongTimeStamp,
TO_STRING(TimeGenerated, 'M/d hh:mm:ss') AS ShortTimeStamp,
extract_token(message,4, ':') as Drive,
extract_prefix(extract_token(message,5, ':'), 0, ' Handle ID') as path,
extract_prefix(extract_token(message,12, ':'), 0, ' Client User Name') as user,
extract_prefix(extract_token(message,13, ':'), 0, ' Client Domain') as domain,
extract_prefix(extract_token(message,15, ':'), 0, ' Accesses') as LogonID,
extract_prefix(extract_token(message,16, ':'), 0, 'Privileges') as Accesses
from *.evt"
-i:EVT -o:csv  -resolveSIDs > output.csv
 
Thanks.  This may do it for us.

If you don't mind using a cryptic but powerful utility, do a google search for "Log Parser" or go here:
