I'm having trouble with DRI and AGP with an intel E7221. My xorg log says that /dev/agpgart is not created. Video works ok, but I'm trying to start "desktop-effects". Here's a section from my xorg.log:
(II) I810(0): detected 8060 kB stolen memory.
(WW) I810(0): Detected stolen memory (8000 kB) doesn't match what the BIOS reports (7872 kB)
(EE) GARTInit: Unable to open /dev/agpgart (No such file or directory)
(WW) I810(0): /dev/agpgart is either not available, or no memory is available
My video card was not supported at all in FC3 and FC4 (only vesa), so I'm catiously optimistic.
