ATI freeze v 3D hrach na Mandrive 2009

Drahi linuxacki priatelia.

Do skupiny problemov s ATI kartami, chcem este pridat aj ten svoj. Prosim Vas preto o Vasu odbornu pomoc.
Nainstaloval som si Mandrivu 2009 spring s tym, ze aspon skusim tento system. Vsetko prebehlo vramci noriem, no prve problemy nastali s detekovanim mojej grafiky. Mam nestastnu Ati radeon mobility HD2300. Mandriva ju rozpoznala ako Mobility Radeon X2100. Fajn, kym to bude funkcne, nevadi. Funkcne to aj bolo, dokym som si pokusne nespustil Nexuiz a Glest. So zapnutou 3D podporou som si Nexuiz zahral asi 15 sekund. Potom prisiel freeze a obraz navzdy zatuhol. O Gleste ani nehovoriac.
Mandriva ako ovladac pouzila RadeonHD. Skusal som aj fglrx, ale nepochodil som. Cital som niekde, zevraj vyhodili podporu tejto mojej kraty...alebo take nieco.
Po vypnuti 3D podopry som Glest spustil, ale uz len v menu bol pohyb mysky tragicky sekavy.
Prosim Vas preto o radu, ci sa s tym nieco da robit.
Pribalujem aj moj xorg.conf
Vdaka
