Once the operating system is running no video bios calls are needed.
It's all only about initializing the graphics hardware in first place.
Today's graphics cards need complex ram setup, mode initialization, etc.

The x86 emulation would be running as part of LinuxBIOS, or as a user
space program. Once video is initialized, Linux can take over the
hardware and use it's own drivers (which are not capable to initialize
the hardware from power on)
