clearly this needs to use ioremap_wc(), I was assuming nothing else....
(code mapping things uncached and then frobbing the MTRR's underneath really shouldn't
be allowed to live from 2.6.26 and forward. Esp for the 3D drivers we KNOW that we
want _wc so that is a clear case of just fixing the code to do the right thing)
