radeon driver: checkpoint

[Matthieu Herrb]

>> I've just check out ati-1-0-branch again. And it's back to usable.

For me the ati-1-0-branch is still worse than the driver from 6.9.
I'm using a Radeon 9200 card on an amd64 machine under OpenBSD.

The 6.9 driver works in mergedfb mode, but not in traditional multi head 
mode (with one screen per head (this used to work in 6.8.2)):  it 
produces a corrupted display on the 2nd head, or just mirror from the 
1st, depending on the options.

With the current code from the ati-1-0-branch (copied to the monolithic 
tree and built from there, if it matters), my merdedfb setting, results 
on the 2nd screen always mirroring the 1st, although I specified 
otherwise in xorg.conf.

The dual-screen settings results in no video signal at all on the 2nd 
head, although the log file indicates that the 2nd monitor is probed 
correctly, and that it seems to setup up a correct mode for it.

xorg.conf and log files for both configurations are there:

<http://www.herrb.com/mergedfb.Xorg.0.log>

<http://www.herrb.com/multi.xorg.conf>

Thanks you for your help.
