rivafb results in black screen

Hello,

I have a Geforce Ti4200 with a LCD attached to the DVI-Connector. My
computer is running Debian with kernel 2.6.10. I compiled the rivafb-driver
into the kernel. But when I boot, I see only a black screen.

debian:~# dmesg | grep rivafb
Kernel command line: root=/dev/sda2 ro video=rivafb
