[SLE] Help : Matrox G450 not detected by SuSE 9.0

Yes SuSe 9.0 Pro is available in France. I installed it but : My Matrox G450 is detected as a G400. When I try to change to G450 with SaX2, I get an error message : /dev/apm_bios couldn't be open ! This device exists ! I copied my file XF86Config from SuSE 8.2 to SuSE 9.0 and reboot. The card is detected, DRM works. But if I run SaX2 test the system freezes ! There seems to be a bug in SaX2, even after the available upgrade. Did someone meet the problem ? I'll report to SuSE. Thanks for your help. Michel.
