If your card is not supported, you may want to try passing: video=ofonlyin the append line to the kernel. It should then use the already initialized screen from OpenFirmware.
If your card has a DVI along with a regular DSUB15 VGA output, make sure that the machine does not detect the wrong output. This happend to me with a ATI Radeon 9200SE PCI MacEdition, my 43p Model 150 randomly chose one on boot time but never probed both properly.
Another card that works, is a Rage128 PCI usually found in older B&W G3 Powermacs.
In any case, I second Sven's suggestion to use a serial console as it is probably the most reliable solution.
