- activate Option ROMS correctly.
- de-obfuscate the Option ROM image selection code.

MEMIO space from working at all.

is not long long on all archs. (They happen to be long's on 64-bit arch's
and gcc considers that significant enough to warn about it.) These should
probably be uintmax_t but I didn't feel like adding all the extra includes.
these were cosmetic. However, at least two of these changes fix bugs
where a (fake) pointer to a RX descriptor was added to the physical
memory start address with the cast in the wrong place resulting in
rxdesc[pmem_start] instead of (uintptr_t)rxdesc + pmem_start.
just limited to the DEVICE_POLLING case. This removes the FXP_RFA_RNRMARK
hack, and replaces it with a softc flag that is used to record when
the handling of a no-resource condition was deferred due to running
out of DEVICE_POLLING cycles. This was tested on -stable, but the
code is essentially the same as in -current. It should only affect
the case where DEVICE_POLLING is defined.
The details of the mechanism behind the crashes are still uncertain
but the most likely cause seems to be some kind of hardware confusion
when the no-resource recovery code is accidentally invoked while
the receiver is still active. This could have happened if the
hardware left the 0x4000 bit of the RFA status word set. The comments
in the commit log for revision 1.142 stating that the driver could
clash with the hardware writing to this status word were not correct.

from being MI in any fashion. It currently "assumes" that it can get
a kernel virtual address for a phyiscal address by adding KERNBASE to the
physical address. It also tries to read values out of a the PC BIOS on
all archs. It also uses "manual" inb() and outb()'s to talk to the mcclock
device which just happens to be at that location on both i386 and alpha.
This driver should likely be i386-only.
