Re: No valid MMIO address in PCI config space

Well, here is a fix. Problem was that on alpha lines in
/proc/bus/pci/devices are quite a bit longer (format for "long"
is "%16lx" vs. "%08lx" on 32-bit platforms), so they don't fit
in the fgets() buffer. Apparently lnx_pci.c was written and
tested on some 32-bit system. ;-)
With this patch all that "resource overlap" weirdness is gone.

Ivan.
