Interesting.  This implies that the failure is very early in stage 2, or 
during the transition from stage 1 (setup) to stage 2 (decompression.) 
This is also the point at which transition happens from 16-bit real mode 
to 32-bit protected mode.

This could imply either that something is going on clobbering high 
memory, or the protected mode transition failed.  Either is a Very Bad 

Are you using the syslinux menu system at all?  If so, does it work on 
this machine?
