Not really.

It is certainly possible to create a video card driver that does not rely on an onboard bios or OpenFirmware roms.

We did this in the '80's with Peter Stark's PT68K2 (which used a 68K processor and an ISA bus) when we wrote drivers for ISA ET-4000 video cards that completely ignored the bios roms.

Detection is the toughest part of this equation, and addressing variations that can be covered via bios calls have to be dealt with via software, but as we did this almost three decades ago it certainly CAN be done now.
