r600 drm module ERR for 2.6.32

hi,
i heard that new kernel has the 3d acceleration (finally) on r6xx series, and my chip is rs780 (aka AMD 780G/HD3200).

running "glxgears" within Xorg getting me an error:

do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try adjusting the vblank_mode configuration parameter.
drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info.

dmesg below:

[drm:r600_cs_packet_next_reloc_mm] *ERROR* No packet3 for relocation for packet at 47.
[drm:r600_packet3_check] *ERROR* bad SET_CONTEXT_REG 0x28014
[drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

i can confirm that KMS is enabled because switching between ttys is indeed *very* fast.

I think you need to get more than just the new kernel to get 3d acceleration, there is a thread about that http://bbs.archlinux.org/viewtopic.php?id=79509
