i.e. glxgears might be helpfull.
You have the module "dri" loaded, which shouldn't be done
as far as i know, but since it works for you with a non-xen
kernel, disabling this option probably won't make a difference
(however, you should delete this entry nevertheless).
BTW.: the log file complains about the unknown/unused
option "UseFBDev". You should delete this entry (but it
won't make any difference)
Otherwise, i didn't found anything suspicious in the kernel log.
