I got the same on a IBM ThinkPad T20 (Dapper, happend with all kernel-versions, Breezy was fine). As the T21 has also a S3 Savage chip, it seems to be the same Bug as in 33617 (sorry, dont know how to insert a link).
so it is definitely related to DRI. (disabling DRI resolve the problem)
I found some further information on thinkwiki.org (www.thinkwiki.org/wiki/S3_Savage_IX8)

   Option "BusType" "PCI"
   Option "DmaMode" "None"
in xorg.conf also resolve the issue but DRI is still disabled

hopefully you may further investigate the bug with this information
