Hi,
I'd like to point out this proposal for a reworked kernel graphics
subsystem.

One of the many interesting posts in the thread:
http://lists.duskglow.com/open-graphics/2006-August/007196.html
While some work is needed to rationalize the current mess, I don't
think that too much of the graphics system should be in the Kernel.
Currently, X11 can crash and not affect the Kernel at all. This
shouldn't change -- a new graphics system shouldn't pull the Kernel
down with it if (make that when since graphics is much less stable
than the Kernel) it crashes, the Kernel must survive the crash.
Does it really matter all that much? If (when) my X hangs, I have to
reboot the system to get the system back to a usable (i.e. with a GUI,
this is a desktop workstation) state, even if the kernel is still
running and I can still access the system over the network. Unless the
kernel can clean up after X and put the hardware back into a workable
state.
Hanging and crashing are two different things. At least they are to me.
Hanging would mean that both the mouse and the keyboard don't respond.
Crashing, the screen goes black, the X session shuts down and either
you are returned to the console or the display manager restarts the X
session.
Yes, I processionally have problems with the keyboard that are only
cured by a reboot. I really hate it when that happens. But usually, X
either crashes clean or I can restart it without a reboot.
Note that on a system that must be up all the time that X hanging can be
cured with a watch dog.
