IIRC, that you need bleeding-edge DRM modules for i915tex to work. These
modules are not even in 2.6.22. Are you sure it worked?

These 256MB of VideoRAM are probably related to the AGP aperture
(possibly configurable in the BIOS). I guess it's only a maximal amount,
not what the driver actually always uses when it needs less.


Also, please note that 2:2.1.0-1 has been uploaded to unstable (a little
bit more recent than 2:2.0.0-6).
