Merged the mga-lock-debug-0-2-0-branch with the trunk. This includes
several fixes including: (Jeff) Really disable multitexture (Broken since Mesa 3.4 integration.) (Jeff) Various changes in mga_state.c in the kernel module, which includes a fix to the bug where the first OGL application hangs the machine w/out rendering anything. This also includes defines for the warp registers so they are easily human readable. (Rik and Jeff) Fixed all the schedule loops in the kernel to look like they are supposed too. (Jeff) Configurable agp modes: Add the option "AGPMode2x" or "AGPMode4x" to your XF86Config file. (Rik) Various cleanups to the mga kernel driver to make it easier to read and debug. (Rik) Removed alot of DRM_DEBUG statements from the kernel driver.
