Wasn't there an issue with some MB's putting a hole right at 16M
for video or something and that caused FreeBSD to ignore everything
up higher? And I think it was Compaq's that had the problem...

Seem to recall the solution was either to turn off all caching of
BIOS EPROM and video in the BIOS setup, or David Greenman had a
kernel workaround that statically allocated the "hole" to nothing
and forced everything to run around it.

Or most likely I'm totally off the wall and don't know what I'm
talking about.  :-)
