Here is an lsmod with exactly the same situation when
the oops occured,
I have done one thing I can remember that may be not fair with
the kernel : "/sbin/modprobe sis-agp agp_try_unsupported=1"
    agpgart: Trying generic SiS routines for device id: 0648
    agpgart: Maximum main memory to use for agp memory: 941M
    agpgart: AGP aperture is 128M @ 0xd0000000

but I don't know if agp is used in my case.
I will retry today the same tests without agp...

so when the oops occured for sure : I was using :
at no load:
exportfs nfsd parport saa7134 ntfs ieee1394 v4l tuner usbcore ov511

low load :
sis900 e100 crc32 iptables i810_audio

unknown load (how to know if my agp port is used ?): 
    sis-agp agpgart loop/isofs(maybe) 

high load: ide_cd cdrom, 
and harddrive(hard in the kernel, not as module)
CPU/memory bandwith was at 100% because of encoding with
transcode.

Ask me more informations if you need, as I am not a kernel hacker .. :),
