Oh...do we know the "sizes" of all

Ok.

ok. I'll keep that in mind.

Jeff,
Thanks for trying. I'll r
Just tested your patch on an x86 laptop with two CardBus controllers
(kernel's CardBus bridge code == kernel's PCI-PCI bridge code, for the
most part) and an SMP x86 desktop machine.
The patch worked 100% on my laptop, but failed to allocate a PCI memory
region on my desktop machine. Two attachm

Hi all,
This patch contains the support parisc-linux needs in PCI generic.
My patch is not as clean as I'd like - but it should work.
Please send changes/feedback directly to me.
Code in parisc-linux CVS (based on 2.4.0) does boot on my OB800
(133Mhz Pentium), C3000, and A500 with PCI-PCI bridge
