The PALM firmware is supposedly Northern Islands series, the 6310 seems to have been manufactured about the time these were introduced on the market. Radeon support has been further developed since 3.8. But it's some work to import the code, which may be an understatement, I'm definitely not an expert but casual browsing it seems the threading calls need changed, and these drivers use the i2c interface which AFAIK has been deprecated in FreeBSD for some time. -- Waitman Gobble Los Altos California USA +1.510-830-7975
