Render acceleration ATI
hi guys,
i tried to dig more into my problem (non-functional acceleration with
xorg 6.9 and EXA render acceleration on ati x600.
the card seems to be recognized by the radeon kernel module. drm
doesn't recognize it, as it seems, although both radeon and drm modules
are loaded. AGP and AGP_AMD64 are compiled into the kernel since they
are automatically included with IOMMU.
i found following post on LKML:

>>>>
Now that Xorg 6.9/7.0 has been released, DRI is supported on more Radeon
cards without ATI proprietary drivers. I got my X300 to work without
problem. But, another Radeon X600 required to add its PCI ids to the
Radeon driver. Patch is attached.
I can't be sure about the "CHIP_RV350", I copied it from the X300 entry
(from http://dri.freedesktop.org/wiki/ATIRadeon, X600 is a rv380 chip
while X300 is a rv370). But, at least it works now.

when i check the output of lspci -v/-n i get the following on my box

i wanted to try to add the PCI ID of the card to the respective header
file mentioned above, however i'm not sure which of these two... at the
moment when the lspci -v/-n was executed i had radeon and drm modules
loaded as i stated above.
i'm not particularly skilled in these things - do you thing that this
will work? are there any other procedures necessary? which of the two
numbers should i add to the drm_pciids.h?
thank you for any advice. regards,
