I see the exact same error with 2.6.28-rc3. X works fine with 2.6.27.x kernels and the same xorg.conf setup. This is where it breaks on 2.6.28-rc3 kernel: (...)

Hum... This happens with SiS 651 on kernel-2.6.28 (tested with rc8, rc9 and final). 2.6.27 worked smoothly. See bug #12372
After reading bug ♯11958, I'm wondering if the fix for a machine hasn't broken another machine...
