Cannot load radeon module: Unknown symbols

[pigah]

I'm running debian sid on Thinkpad T60 with an x1300. I'm trying to get accelerated 3d and 2d running and have loaded the xserver from experimental and run the easy-drm program to get the latest kernel modules, but when I try to load the radeon module i get:

FATAL: Error inserting radeon (/lib/modules/2.6.25-2-amd64/kernel/drivers/char/drm/radeon.ko): Unknown symbol in module, or unknown parameter (see dmesg)

in dmesg I get a list of unknown symbols (see below). This is driving me nuts. Any help would be welcome.

Make sure you installed drm.ko and radeon.ko

Make sure you installed drm.ko and radeon.ko

Hmm, your suggestion made me try manually loading these modules using insmod and it works. Why does it work and modprobe doesn't?

You probably have to run "depmod -a" to make modprobe aware of the dependencies. Other than that it was maybe just a question of loading the drm module before the radeon module.

Thanks for the suggestions, turned out I had blacklisted drm by telling modprobe that it was loaded when it wasn't, so that the symbols weren't there when radeon tried to access them.
