The
open-source RadeonHD driver that is even supports the
Radeon HD 2900XT has continued over the past few days with a number of changes. Among these changes has been adding identification support for new GPUs (including the Apple MacBook Pro 2.2), removing some experimental checks, adding the
conntest utility, and this morning AMD's AtomBIOS parser was merged into the
xf86-video-radeonhd git tree. This AtomBIOS parser was written internally at AMD but is now available as open-source code. Check out the RadeonHD git code if you want to try out an open-source driver for ATI's R500 and R600 graphics processors.
