Yes it is against a 2.4.2 tree right now. I plan to place into 2.5.X. Note
the api for fbdev has changed to make the drivers simpler but you can back
port a ruby fbdev driver to standard 2.4. Their is a fbcon-accel.c that
does this. It requires a little patching to fbcon.c tho. I plan to use
fbcon-accel.c at first for 2.5.X or if some driver writer is brave they
could make it part of their driver for 2.4.X now. Also under ruby it is
possible to use /dev/fb without fbcon. I did it with vga16fb and vgacon to
test the fbdev driver. The fbdev driver has to be able to set the video
state back to vga text mode. This can be done in a function that can be
called when the module unloads and when you close /dev/fb. Please note
ruby is a developement kernel which needs more work.

renders the sufferer barely able to perform the simplest task. 2. A disease.
