Display turns black when X starts

Hi!

I have quite annoying problem. Starting since 11.0 -> 11.1 upgrade.
On startup display turns all black when X starts, if full 24bit colordepth and radeon -driver is used.

When using less than 24bit colors or vesa or ati -driver, it works, but there are performance issues.

Everything worked well on 11.0.

Computer is Compaq Evo N1015v and graphics card is apparently ATI IGP 320M (ATI RS100 4336)

And here is my xorg.conf:

Allredy tried “Sax2 -r” and I have updated everything to latest stable versions.

Solved! (Hopefully:)
