The docs for mtrr say that it can speedup graphical usage upto 2.5, and
the Docs provide examples on howto read/add to /proc/mtrr, but are there
any apps that make use of it? or do all you have to do is turn on the
config option and then turn it on like the file says it would be used by X
(or would it need a patch to use as well as manipulate?) and framebuffers?

It's not something that programs have to support, it just works. Try
benchmarking with and without mtrr. You should see a big difference
on some operations.
