* bootloader/pci.c: Re-instated code that prevents remapping small
IO regions, which if remapped would cause i8259 registers to move
out from under the #define'd base addresses.
* startup/bspstart.c: Reduced BAT2 PCI memory allocation to 256
megs, I incorrectly had extended it which would cause problems with
PCI devices that defined prefetchable memory.
