Hello,
Could anybody explain why aty128fb is so slow?
I'm using kernel-2.4.20.

01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 Pro TF (prog-if 00 [VGA])

Computer has Athlon 1.8+ processor on K7VTA3 motherboard.

In directory with 5000 files ls on console takes more than 6 seconds.
In xterm or rxvt ls takes only 0.6 s.

Because the driver is completely unaccelerated. Everything is drawn pixel 
by pixel :-( 2.5.X is much faster :-)
