I have the same issue here after upgrading to Jaunty and tried upgrading to Mario's PPA for Mesa, the XSWAT teams stable Xorg drivers PPA and the 2.6.30-rc4 kernel from the Ubuntu kernel team but sadly none of it helped. In the end the only solution has been to disable DRI for the card.
This is a "ATI Radeon 9250 5960 (AGP)" according to Xorg.conf and an "ATI Technologies Inc RV280 [Radeon 9200 PRO](rev 01)" according to lspci. Worked happily with previous releases.
