I've heard of this type of problem.  In the cases I've heard of I believe 
it was h/w related (essentially the way the ram is designed vs the way the 
board sees it).  Hopefully this is not the case.

In the hopes it is a bios bug or a ram size detection problem you can tell 
the kernel to believe it has a certain amount of ram regardless of what it 
detected.

Pass mem=256M to the kernel.  If you don't have 256MB or more memory 
actually installed the box will crash eventually when doing this.  So pass 
this parameter then run a job which gobbles memory.
