ATI console framebuffer with Debian Squeeze

In order to have a native resolution console on ATI hardware you just need to install one package that adds KMS support:

sudo apt-get install xserver-xorg-video-ati

This installs some X.org related stuff but also a module that adds console framebuffer support on widescreen resolutions, etc etc.

The conf file is:

/etc/modprobe.d/radeon-kms.conf

Cheers
