Yes, it works wonderfully:

built against pulled this morning (05:30 BST)
2.4.4-pre3 (BK yesterday)


Please note that "make World" fails for me (with build Servers only as an
option in host.def)  [the mesa stuff, amongst other things falls over]

However, the drivers build and I copied ati_drv.o, ati_misc.o over Kaoru's rpms.  (I also copied libfbdevhw.a - but, of course, that no
longer loads).



+ no more flickering lines 2cm from left of screen
+ excellent scroll acceleration.

I'll do X11perf if you're interested - otherwise there's plenty of other
things to do... ;-)

Two points:

1/  the cursor disappears after about 5 seconds __only__ when it's over the
active window (it stays there fine when over an inactive window or the
desktop) -- KDE 2.0beta.

2/  how difficult would it be to plumb the scroll acceleration back into the
console driver?  (would one need access to the NDA stuff?) -- the scrolling
of console is a real problem in blocking sound :-/

thanks for the excellent work,
