revision 1.9 when split the code into separate #ifdefs for single
CPU and multiple CPU. Comments on the patch are:

Also added a hack to keep the OpenBSD timer problem from filling the log.
The new PIT seems to work, but until some
enhancements are made to the way the timers
and devices.cc work, it'll be slower than
the old one.
- add bx_instr_inp2 and bx_instr_outp2 which actually report the
values that were used in the I/O operation! I made new macros
and functions instead of changing the existing ones on the slight
chance that somebody already has code that uses the old ones.
The original code for determining the capacity of a disk only worked for
ATAPI drives, leaving us poor SCSI users in the cold. The code uses the
standard Linux CD-ROM driver routines, so it should work on any supported
drive. It's basically just a copy of Keith Jones FreeBSD code.

for Linux!!! I tested this using host OS kernel 2.2.14, and was able
to use telnet, ftp, irc, lynx, etc. Because it is a packet filter
solution, you aren't able to talk to the host machine, only to other
machines on the network. The patch itself is in
patches/patch.ethlinux-splite.
X servers that I've seen, however on other X servers it makes all
key mappings into absolute junk. We need to continue to work on this
patch to support all X servers and all key maps.
