Hello,

Currently, on an old laptop I have this chip:
01:05.0 VGA compatible controller: ATI Technologies Inc
Radeon XPRESS 200M 5955 (PCIE) (prog-if 00 [VGA controller])

using ati-drivers, all if fine with:

 xorg-server-1.5.3-r5
 ati-drivers-8.593
 xorg-x11-7.4
 linux -  linux-2.6.28-gentoo-r5/

I want to convert to the open-source radeon driver


I'm not finding instruction docs (except very old) so here's
what I have found to do.

edit /etc/make.conf:

VIDEO_CARDS=radeon vesa
(I keep vesa for a backup)

emerge -C ati-drivers

run 'qlist -I -C x11-drivers/'

and rebuild the list of supporting drivers?
reboot

???  that simple or did I miss something?


One more thing.  Enable DRM support in the kernel and select the Radeon 
DRM driver.  You need this or else you won't get accelerated graphics.
