An OQO?  *drool*  I bet nobody has ever tried Xen on one of those before :-)

I don't suppose you can find another Transmeta machine to test this on?  Or is 
anyone else out there actually running on Transmeta at the moment?

Yes, that'd be favourite if the OQO supports something as arcane as a PC 
Speaker - just have your debug output beep to say "I'm still alive!".  I 
imagine you can cause a beep reasonably simply from the ASM, although I don't 
know how ;-)

What have you tried so far?  Have you tried removing use of the global bits as 
Ian suggested?  Have you hacked the CPUid checks to allow the Transmeta, or 
is it definitely not booting that far?

Cheers,
Mark
