Hello, I can't get any video acceleration on my ATI 4550, journalctl gives me:

mars 29 19:19:34 localhost.localdomain kernel: [drm] VGACON disable radeon kernel modesetting.

mars 29 19:19:34 localhost.localdomain kernel: [drm:radeon_init] ERROR No UMS support in radeon module!

Here are my spec :

AN8 Asus Motherboard + Athlon 64 3500+ ATI 4550 GC 2 GO ram (Corsair XMS) 250 WD HD

Thank you !

/var/log/Xorg.0.log could offer more clues, you can upload to using fpaste /var/log/Xorg.0.log and post a link to it here. Also dmesg | fpaste.

Thank you Ahmad for the reply, Here is what you asked for :

I must add that I had to use the basic video mode to boot on the livecd (last updates ones) and I'v found out that grub is booting fedora with nomodeset, but the system simply won't boot past fedora logo if i remove nomodeset.

Okay i found out that I had to remove nomodeset and put instead thank to muep on #fedora irc channel. The issue is only partly fixed because now I guess that audio over HDMI is disabled.
