Cool.  I think you mean 284034 and not 280434.  It certainly looks
suspicious.  I'm trying 284028, but it'll be awhile.  It wouldn't
boot
with just the kernel, so I'll try building world as well.

Yes, I did.

I can now confirm that 284034 is the culprit. Unfortunately, that single
commit MFCed 10 updates of which 6 may be the problem. I tend to suspect
the PCI changes rather than the CardBus patch, but I will spend a little
time looking at the individual commits in HEAD to see which, if any, touch
both PCI and CBB.

Adrian, I don't have the ability to test on head ATM, so, if you have a
chance, go for it. Most if this is way beyond my ken, so I am extremely
unlikely to spot it.

I am adding jhb@ to the CC as 284034 was his commit.
