I've noticed the same problem with [Radeon Mobility 7500] [1002:4c57], compiz doesn't work by default but after setting SKIP_CHECKS=yes it works without any hardware specific issues.
That 036_blacklist_ati_on_laptop.patch has introduced a bad regression :-(
It would be also very useful if somebody with the card ATI Radeon Xpress 200M (PCI ID 1002:5955) - which was the reason for the patch in first place - could test with the newest driver and possible with EXA (as kostas suggested).
