Last December I spent few nights looking into it, but eventually got
stuck @ GPU initialization routines (IE the stuff where it writes proper
configuration to registers) and decided I better spend my time on
something that pays my rent... ;)

Anyway, here are the "stub" patches so far:
http://plaes.org/files/2011-Q2/0001-Initial-stub-for-Geode-LX-modesetting-driver.patch
http://plaes.org/files/2011-Q2/0002-Initial-init-for-Geode-LX-modesetting-driver.patch

Päikest,
