THANK YOU SOOO MUCH!

After looking at the mentioned file and afterwards in DRI of r128 (2.4.9
kernel), I found that this IOCLT is indeed implemented for r128 and can
transfer data in both directions.

OTOH, the DRM part of the r128 driver doesn't seem to take advantage of this
at all. Radeon does, but only a little as far as I understand the code. I s=

a lot of potential in this.

Now I only need to learn how to allocate these buffers properly and initial=

the structures and it should work.

Thanks to all who replied.
