hp probook - no clt-alt-f1

hi all, once again I need you guys help. from work i got a HP ProBook 4710s. It has an ATI Mobility radeon 4300 series graphics card. The thing had Windows7 on it and I made the world a better place by replacing that with OpenSuse 11.2. The issue is that when pressing ctl-alt-f1 to f6, I only have a black screen, no console. I played around with sax2 , xorg -files and resolutions, but to no avail. On ctl-alt-f7, everything looks fine, I got a nice image. when I type init3 on the grub-screen, it also goes to normal graphical screen. Help anyone? I cannot work without the crl-alt f
