I installed xorg-server 1.2.0 from the testing repository.
I was able to start X, and everything was working, but very, very slowly.
I looked into top and realized that X process eats lots of CPU.
This is confirmed by another person in this thread:
This is probably related to open source ATI Radeon driver.
My system:
- latest stuff from current repository and testing repository
- Athlon 3000+
- Radeon 9800 Pro using DRI driver
- kernel 2.6.20 from testing
This task depends upon

Not sure if this is tha eaxact same issue (different symptoms), similar to lumiwa in this thread: upgrading to kernel26 2.6.20-1 seemed to cause X to crash at startup. ATI Radeon driver/xf86-video-ati used. Downgrading things like xorg-server 1.2.0-1 didn't help, only downgrading to kernel26 (so everything except kernel26 is currently up-to-date testing). I hope that the info. I provide is of some use. Thanks.

could you try to downgrade just libx11 from current to libx11-1.1-2?

I can confirm this, however, if I disable exa it's a lot faster (with an X800XL & the opensource radeon driver).

As EXA is still not the prefered rendering method, I don't think this is a big issue. I haven't found any problems with a radeon X550SE, either with the fglrx driver or the opensource drivers.

I have the same issue with sis650 video... May be this is xorg upstream bug?..

Now it's even worse, because new version of xf86-input-keyboard and xf86-input-mouse doesn't work with xorg-server-1.1.1, so I will need to skip 3 packages in my updates now :(
