Performance of radeon free driver
The other day, i updated to KUbuntu gutsy and saw it ships a free graphics driver for my Ati X300 card (r300 based). I switched to it from the non-free driver but i have went back.
Why? Well, actually it does work, but it is slow, for example, hiding and showing again a normally sized ktuberling, takes around 180ms on the fglrx driver while it takes 550ms on the radeon driver.

RadeonHD Weekly Progress Report
As there's been a RadeonHD article at least once a week (from the Ubuntu installation to the Conntest utility) on Phoronix since the RadeonHD driver was introduced, it's almost becoming a weekly progress report here for this official AMD open-source R500 and R600 driver.
Last week when talking about the RadeonHD driver there were about 90 commits to its xf86-video-radeonhd git tree the entire week and just today from the Novell developers we have seen 26 commits in the past day.
Aside from today's work, there was a fix earlier in the week so the AtomBIOS would build on OpenBSD, adding new product IDs, and fixing other broken areas. With the latest git code this afternoon we had tried it on an ATI Radeon HD 2600PRO 256MB graphics card, but it presented a gloomy situation.
