AGP 1x ? (was Re: radeon graphic speed regression 2.4 -> 2.6 test7 benh)

[Soeren Sonnenburg <debianppc-ml@nn7.de>]

Hi...

I recently upgraded to -test9 but it is also as slow as test7. Then I
noticed the AGP 1x line 

Nov  2 12:37:39 no kernel: agpgart: Putting AGP V2 device at 0000:00:0b.0 into 1x mode

and I got confused as I had to set AGP 4x some months ago in the X
config to have resume after sleep working. Now setting that AGPMode
option to 4 freezes X. (now also under 2.4!).

I could not test 2.6. with the old radeon driver as it did not compile
through. Also X is running at niceness 0...

I am now back to 2.4 as I have no more ideas what to try/how to help and
2.6 is not usable in this state...

I attached my XF86Config just in case someone else wants to reproduce
the problem. That config opens up a display on :0 and :1 if a monitor is
attached. However DVI is still not working. The problem occurs also if
no monitor is attached. Tests ran on internal DFP only...

Regards,
Soeren
