Hi,

got a 

01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon
X1300/X1550 Series]

card and tried to use KMS and radeon since its in the mainline tree but got no
luck yet (using ubuntu maverick Xorg 7.5 + radeon 6.13.x).

In X Screen does have some black lines running over the screen every time -
reading some text on white background is really hard because of these black
lines running through the screen everytime, hope you know what i mean.
This does happen with and without using KMS.

The only configuration which is usable in terms of you can do your work >1 hour
is to disable KMS and using the "old" radeonhd driver (git tree) - which does
work fine and without those "glitches".
Any help or information i can provide to make radeon "work" like radeonhd to
get rid of those "black" lines running over the screen causing headaches?
