I did Alpha platform support for approx. 7 years before leaving the mothership.

pciutils requires the use of syscalls to do pci config cycle accesses because
Alpha systems memory-map the PCI config space into it's uber memory address space;
i.e., Alpha *always* did pci-mmconf; it never used io-mapped, address+ data regs
to do PCI config cycles.
Which reminds me, since Alpha doesn't have equiv. iob/w/l instructions, the PCI
IOPort accesses were memory-mapped as well.
Similar stuff/issues with PCI on PPC.
