In theory it should work fine. In practice some X-Servers have problems
to restore the video mode correctly. Maybe due to some hardware problem
(some video boards you can't ask about the current state), maybe becauce
they don't expect the console being in graphics mode. You'll end up with
a broken console then. This problem is'nt new...

I never had problems to mix the accelerated XFree86 Server with fbcon
(matrox mystique, both vesafb and matroxfb work fine). The FBDev Server
works too, of cource.
