Thanks for sending the boot log, and sorry for 
the long delay until I found time to answer!

Hmmm, your VGA card decodes only the LSB of the 
PCI function line information ...

Well, I guess it is time I remove some code from
the PCI code in FreeBSD-2.2, which was meant to
work around some (uncritical) behaviour of the 
Triton I chip set.

If you track -stable, then the problem will be
gone, soon, else I can send you a patch.
