Subject: piix driver oops with 2.5.46

Folks,

I just tried using 2.5.46 with one of my machines, and recieved an oops
with the piix driver.  The machine is working without the driver
currently, but without DMA enabled (hard drives are SCSI, so this only
affects my cd-rom).

Here is the decoded oops, and an lspci from the machine.  Let me know if
there is any more info you'd like, or if I can test anything out.
