Well, I'm not sure what the actual bug is, and it may be due to where certain 
code is physically located meaning that other changes since 5.2-BETA may now 
cause the bug to appear.  When I tried to track down my problems with 5.x 
there were no diffs of any content between 4.x and 5.x in bios.c, but I still 
always got the panic on 5.x.  I think it is some kind of pmap bug or other.
