TODO (in no particular order):
(1) merge the asm-i386/pci.h fixes
(2) fix up the bootmem stuff so current works
(3) fix up the memmap_init() stuff so current works
(4) PAGE_SIZE -align pkmap and kmap portions of fixmapspace to remove
core dependencies on FIX_KMAP_END for aligning addresses.
(5) debug the scatter/gather kmapping calls for COW and anon pages
to reduce internal fragmentation of pagecache
(6) find the problem with ext2 and 64KB PAGE_SIZE
(7) fix q->max_sectors < PAGE_SIZE
(8) audit the rest of drivers/

because some specific tests were scheduled on the hardware today.)
