Turning KMS on didn't work for me either - I also got mangled fonts plus other corruptions. I attach the output of dmesg, there are some error messages like...

[15318.655652] i2c-adapter i2c-1: unable to read EDID block.
[15318.655657] radeon 0000:01:00.0: LVDS-1: no EDID data

I wonder if we should open another bug, maybe at bugs.freedesktop.org, to see which ATI chips are affected...
