mxser_new, pci_request_region for pci regions
Use pci_request_region instead of standard request_region for pci device
regions. More checking, simplier use.

Correct me if I'm wrong, but that use of ioaddress looks totally wrong to me.
Isn't there a pci_iomap() or something missing?

Both brd->vector and brd->ports[i].ioaddr are used in inb and outb function
calls. They themselves remap a small range (one byte in these cases) and require
ulong addresses as a parameter, not pointer to virtual space, correct?

Possible. I try to ignore that interface completely :) I would feel much more
comfortable if this would be done the other way. But this would probably
introduce more code because this one seems to work on non-PCI devices also.
So just ignore me :)
