Yes it does. I have gotten glxgears running on my 9700Pro a7n8x. Unfortunatly I have not been able to get DRI working. I get the following error in the XFree log;
drmOpenDevice: open result is 6, (OK)
drmGetBusid returned ''
(II) fglrx(0): [drm] drmSetBusid failed (6, PCI:2:0:0), Permission denied
(EE) fglrx(0): DRIScreenInit failed!
(WW) fglrx(0): DRI initialization failed!
I belive this happens as a result of compiling the kernel with a different GCC than the ATI drivers. Damn. If I figure it out I'll post a solution here.
