As far as I'm aware, ddcprobe works fine on xen-unstable thesedays
(though I can't actaully find a machine with a monitor attached to test
it rightnow, it doesn't segfault)
 
I haven't used lrmi. vm86 mode is pretty icky. It's believed to work
under xen/linux, but its possible its not perfect. I'm afraid fixing it
would be pretty low down our priority list...

The first step of debugging this would be to find out why the kernel
wants to return a segfault.
