Xorg log from hung session

Since upgrading from 20100523 (fa552261) to 20100528 (f4bcd0ca) lugaru locks
the machine up solidly, pretty much as soon as the rabbit starts to move.
Anyone else seeing this? (I am using lucid + "radeon gallium" PPA on RV410)

Any educated guess on which commit could have caused this? I can do some
bisecting, but the full machine reset cycle makes it a pain.

By locked up solidly I mean that I have to power off. sysrq-b does not respond.

Still the same with 20100608 (fccfb7b1).

Last message in syslog, not sure if it is related:
[ 3279.852242] hda-intel: IRQ timing workaround is activated for card #0.
Suggest a bigger bdl_pos_adj.
