Try kernel DRM off, kernel AGP as modules. I think ATI finally stopped
distributing its own agpgart. Then you may need to stick your
chipset-specific AGP module into /etc/modules.autoload.d/kernel-2.6.

DRM comes from ati-drivers. libdrm only provides the userland library
and headers.

[gentoo-user] ati-drivers-8.28.8 - How to get DRM support?

[Mark Knecht]

Hi,
  I've been messing with this for a couple of hours now and cannot
find the right combination. I am using the most recent ati-drivers
package since it seems to support TVout, at least on one of my
Pundit-R machines. However since upgrading from a much older and hand
patched 8.14.x driver I cannot seem to get DRI/DRM support to work. I
end up with messages like this and the drm module doesn't load as I
think it isn't built. I believe I have the proper chipset support in
place:

  With these ATI drivers what is the proper way to configure the
kernel? I've tried it with kernel DRI support on and off. Is there
some other setting required to make this work?

  Should I be using a DRM from the fglrx package, from the kernel,
from libdrm or somewhere else?

Thanks,
Mark
