Hi, is there a way to use dri, drm and opengl with this card?

Functionality of ATI Mobility Radeon 7500

I have a Thinkpad R50 with the ATI Mobility Radeon 7500, currently running Gentoo Linux. (and dual-boot with WinXP)

Direct rendering works with both radeon and ati (gatos) drivers, though the radeon is significantly (20%-30%) faster. I have not tried fglrx.

TV-out works with both VESA and ati (gatos) drivers, though both have problems. Using the VESA driver there is no acceleration, and the system is not fast enough to act as a mythfrontend without dropping frames rather badly. Using the ati driver performance is acceptable, but the colors are washed out (practically gone) and the contrast is "odd". The image looks kind like the old "posterization" photo process, where contrast is mostly reduced, but past a certain scale becomes extreme.

In either case, I had to use atitvout to activate the svideo. It complained about VBE, but did the job. I was not able to get both displays working simultaneously.
