So the ATI card is using the fglrx driver, I'm assuming (right?), and
is the intel card using the Intel graphics drivers from intel.com?
I've been told i810 that comes with XOrg is actually better (besides
having full 3d support)... but what intel chipset are you using?  Have
you tried the NON-proprietary drivers?

If its a proprietary driver, my money is on a buggy driver that
doesn't cooperate with the kernel.

So xorg quits, but the monitor stays frozen?  Or the xorg process
doesn't die?  If its the latter, can you just send it a KILL (try an
INT signal first, of course)?  Anything in dmesg or the XOrg logs?
Can you grab the XOrg pid with gdb and get a stack trace?  Can you
switch over to a console (ctrl-alt-f1, typically)?
