VMWare requires you to install a special proprietary X server they created
on the guest to get X Windows running in FreeBSD and Linux.

Could you run 2.4 in it and run plex86 in that and figure out why it's
not working? At least the part about getting the pages (host_reserve_page
if my memory serves correctly) is a bit wrong at the moment.

Please do :) quite cool. Have you tried more advanced stuff like X?
Probably Windows isn't far behind... and how about, more generally,
a test suite of a bunch of combinations of assembly instructions,
and also invalid codes and other erroneous stuff, that both plex86
and bochs, and maybe a normal CPU could run and test if the worst-
behaving code works. If that succeeds, then sane code like Linux
(and I might even say Windows also, considering that it is compiled
code) should run without any hitches <g>

There would be any reason that they _wouldn't_ boot Linux? I would suppose
it doesn't really matter in the long run, because most people will be
running in mode 1 anyway (unless they are debugging operating systems).
