Be aware that the X stack has quite a lot of dependencies, and you might
need to also backport libdrm, and other various x11proto* and lib*
packages. I've done that for squeeze, it's certainly doable, but can
take a fair amount of time/patience. :)

Having stepped down from X maintenance, that's not on my to-do list, but
I might end up looking into that backporting dance again, should I find
some interested customer; unless someone does the work beforehands. :)
