Ubuntu RAM detection

[Tyler Aviss]

Doh!

Thanks for the reminder, high-mem support was off rather than at 4GB
like it should have been. It's weird because I'm fairly sure that my
previous kernel incarnations had high memory working fine but I must
have done something dumb during one of up the updates :-)

Thanks for the reminder, I'm recompiling now so I'd imagine that will
fix the issue.


Cheers,


TJA
