Daniel,

Here's the command:

mozart:/home/ns# modprobe radeon
WARNING: Error inserting drm 
(/lib/modules/2.6.26-1-686/kernel/drivers/char/drm/drm.ko): Cannot 
allocate memory
FATAL: Error inserting radeon 
(/lib/modules/2.6.26-1-686/kernel/drivers/char/drm/radeon.ko): Unknown 
symbol in module, or unknown parameter (see dmesg)


And here's the output in dmesg:
...

Doesn't look too good...
Sorry, I don't know what to do about it either; could you please assist?

Cheers,
