May be you have a similar problem as me. I get a disorted image on the consoles, like in old times when the monitor-timing was wrong.
Just to be sure: You're using framebuffer-console (the nice SuSE-Startup-screen; Kernel-option vga=0x....).
For me, my problem disappears if I use a quite old version of the nvidia-driver (2960). You can find it in the drivers-archive.
Perhapps it is worth a try.
