OK.. typescript.17vga   I understand.  You have some kind of
ppb bridge card. 
Some bridge cards get *really* pissed when you probe past
device 8 on them.  In
this case yours starts returning made up values.  There is
code in prep to deal
with this on certain known cards, I think we need to add
your card to that list.

look at prep/pci/pci_machdep.c:prep_pci_bus_maxdevs().  see
how it looks for
prep-pcibus-maxdevices?  Now look at the bottom of that
file, you will see
where we set that for some crazy dec card.  Do the same for
yours.

One more hint if you want to debug a little further, in
sys/dev/pci/pciconf.c,
set pci_conf_debug = 1;  The output of that is tremendous,
but very helpful
when debugging devices that spew craziness.
