On my T60 with the x1400 the radeonhd driver will not be loaded correctly. glxinfo says that the mesa driver is loaded.
Why i can't load the radeonhd driver? Do you need a kernel module for this driver? modprobe radeonhd says that there is no module.
You are seeing the correct behaviour. The radeonhd module is for the xorg server, not the kernel so it gets loaded automatically by X on startup, not via modprobe like a kernel module. There is no 3D support in the radeonHD driver yet, so A) theres not kernel modules to be loaded yet and B) as such there no hardware driver for mesa so it falls back to software indirect rendering.

Thank you. That's it :)
So the radeonhd driver is loaded. :)
Figured it out - for those of you who want to run with a monitor section the following works well for my T60:
DisplaySize 314 203
The HorizSync and VertRefresh normally don't need to be specified as this stuff is gotten from DDC.
