Oliver,

Does the PCI qfe card work correctly on UltraSparcs?  Right now, it doesn't
on OpenBSD--probably because of a bridge issue:

If you feel like testing/playing with it, please let me know the results!

Thanks,

Ok, after this problem has some kind of solution (changes in pci.c
needed only), is there any other machine with hme problems? I have
a lot of sparc64 in access I can get for some days, now is the 
chance ;)

I'm also going to review why the additional pci hme does not work
but expect to see a problem somewhere in bridge problems/irq routing.
