Note that this machine has problems for running Xorg with two memory modules, 
as described in this kernel bug report:

http://bugzilla.kernel.org/show_bug.cgi?id=11103

(I've not yet done the test asked by Yinghai Lu)

But it has always worked fine with one memory module.

Do you think it may be related?
