I have managed to reproduce an oops with the following steps:
* Play some old Sierra game inside FreeSCI for a few hours
* Quit FreeSCI
It's irrelevant which audio driver is used for FreeSCI, as the oops
happens with null driver as well.
Pre-empt is off. IO-APIC is off. ACPI is off. 4k stacks is off.
Difference between kernel configurations is minimal: only the new AES
option was selected in 2.6.8-rc3 in addition to those in 2.6.7. Sound
card, according to lspci -vvv:

Any more info I should provide? I'm willing to try if there's a patch to
fix this.
Below are three ksymoops-processed messages. First was 2.6.7 with
normal audio driver (defaults to OSS). Second was 2.6.7 with null audio
driver. Third was 2.6.8-rc3 with null audio driver. Normal ksymoops
whines about not specifying files are omitted.
