Here are the results:

I've applied only this last patch to kernel 2.6.33 and obtained a black screen
just before gdm start. Then I've tried to apply all the available patches
published here at bugzilla and almost all of them failed to apply except
0005-setup_gart_like_pre_kms.patch and yours, but again, obtained the black
screen at the same moment. Then I went back to kernel 2.6.32, applied all the
patches, and then it worked. I'm using libdrm, mesa and xf86-video-ati from git
head.

Which kernel are you using? I would like to test your same environment, because
after all, KMS is working but I only get 175 fps with glxgears, and 2D
acceleration seems quite slow.
