Works for me - I have a machine with ATI onboard hd3xxx graphics and I was suffering from the above oops. Fixed now with kernel -219 - and I even have working kms now.
Updating to 2.6.31-0.219.rc9.git2.fc12.x86_64 on a RV620/HD3450 box solve the above oops. modesetting works; dmesg : --- [drm] radeon: kernel modesetting successfully initialized. [drm] Initialized radeon 2.0.0 20080528 for 0000:01:00.0 on minor 0 ---
Retested with new testday i686 LiveCD: 01:05.0 VGA compatible controller [0300]: ATI Technologies Inc Radeon HD 3200 Graphics [1002:9610] kernel-2.6.31-0.219.rc9.git2.fc12.i686 xorg-x11-drv-ati-6.13.0-0.3.20090908git651fe5a47.fc12.i686 libdrm-2.4.12-0.9.fc12.i686 mesa-libGL-7.6-0.11.fc12.i686 X now starts up fine with KMS.
