PCIBIOS_INTR_FIXUP was disabled because of instability.
Before recent commitment, both fvdl's machine and my machine panics
with PCIBIOS_INTR_FIXUP.
I think the stability becomes better, now.
But apparently we needs more test. (and possibly more fixes.)

I'm not sure why PCIBIOS_BUS_FIXUP is also disabled.
From my limited knowledge, PCIBIOS_BUS_FIXUP doesn't cause any
problem. (But I don't have experience on a machine which has
multiple PCI buses.)
Does anyone know any problem with PCIBIOS_BUS_FIXUP?

Yup, I'm suspicious about stability, too.
What I meant is that I'd like to make those options stable enough
for GENERIC kernel of 1.5.
(And I suppose PCIBIOS_BUS_FIXUP is already OK.)

I'd like to make those options enabled in both GENERIC and CARDBUS
when 1.5 is released.
But of course, we should not enable those options before enough test.

Thanks. I'll look at your fixes.
