Can you verify the /var/log/Xorg.0.log complaining about infinite loops on 
that machine (that is, when a lockup occours, using ssh from another 
machine)?

If yes, then I'd bet it is the same issue, and in that case it is also not 
Fedora-specific, but a general problem.

I kinda have a feeling that this is a problem with the interaction between X 
and Intel drivers (the EXA vs XAA thing or whatever), or possibly a bug in 
the Intel driver that shows up only in 64bit version.

Best, :-)
