[uml-devel] uml FB

Been looking at the uml-x11-fb patch again.
It still does apply more or less cleanly, but won't build (can't get
Kbuild to play nice) and I was thinking: wouldn't it be easier to just
drop all the X11 stuff and have just a plain in-memory VESA type of
framebuffer in the guest (straightforward contiguous memory region).
This would allow the guest to have a framebuffer and if we need to
actually see its contents, it could easily be exposed using shared
memory. This would completely de-couple the framebuffer from the host,
allowing us to attach/detach as needed: start session, detach, log out
of X, log in, attach to guest framebuffer (although this doesn't address
the mouse/keyboard issue).
Is this (easily) feasable at all?

Thanks
Antoine
