Actually the first paragraph was taken from another post on BLFS-Support
IIRC.  It's not mine, but I didn't quote correctly.

Actually, surprising enough, my video card is an ATI Radeon7000/VE  (Radeon
QY).  Things are lookin good.  I'm not really in need of DRI at the moment
anyways so nothing to actually post info off of except glxgears and glxinfo.
:-$  I am inclined to agree about waiting for XFree-4.3.0, I just found it
interesting that it worked without attempting to do the config as it did not
with 4.2.0.  Perhaps I should have clarified better my intent.  Thanks for
the aditional info tho.
