RadeonHD Driver Introduces Major Changes
 

Following a period of relative inactivity in the
xf86-video-radeonhd git tree over the past few weeks, this afternoon
Novell's Egbert Eich had pushed forward 55 changes to this open-source
R500/600 driver. The AMD Radeon HD 3400 and 3600 series are now
supported and there are a number of other significant changes. The
RV620/635 mode-setting support has required the most significant work
since the R500 series, since all output blocks have been altered due to
the introduced DisplayPort capabilities. We have already tested out this
latest code and were left with a positive impression
