The direct input stuff should be covered by the XINPUT extension
(assuming the people working on that get it fixed in time).

The direct framebuffer access stuff is generally viewed as
a security hole and a pain in the ass for driver writers, particularly
people dealing with OpenGL implementations. Having to support
a DGA-like mode limits what you can do in the driver and unnecessarily
complicates the driver. It's also been a maintance problem and
frequently doesn't work very well with many drivers. Direct framebuffer
access by the client is generally considered to not be the correct way
to do anything, but is just a kludge and it's about time we got
rid of it (should never have been added in the first place). People
making games and such should move out of the DOS age and migrate
to OpenGL.
Mark.
