Ok, there are some overflow bugs in init386().  I think I've fixed them
and will post a patch as soon as I get into my office.  (Alas, can't run
`cvs diff' while on the train :-)

What happened here is that the BIOS reports the amount of memory in KB
units, so init386() multiplies the values by 1024 in a few places to get
byte counts.  Obviously these were overflowing a signed integer.
