I've enabled EXA for my ProSavage chip, and added the "DisableTile" "true"
into my conf file.  It now works, but is really slow.  It disables the DRI
since that requires tile frame buffer.  All seems to be very good, but of
course I cannot as of now use it since it is so slow.  Thanks for the help
to at least get this somewhat straightened out.  I hope that this EXA can
be setup so as to use tiled frame buffer.  At that point I could really use
the card to it's total capacity.
