I have also this problem on my laptop: Dell Latitude C610 with Radeon Mobility M6 LY [Radeon Mobility 9000].
X / Gnome freezes randomly almost every time it is used.
Host is not reachable from network either.
KDE (kubuntu) doesn't seem to have this problem, so is it using X / graphics card somehow differently?
Neither Breezy had this problem.

I'll try also disabling dri from xorg.conf.
