Linux only needs bios services at boot time to get system parameters. It
can use the 32bit APM and PCI BIOS entry points if present, and 2.1.x can
use the VESA 2.0 video extensions. None of these are needed however.

The 2.1.x kernel also supports serial consoles (there are patches for
2.0.x) so you can see whats going on, and LILO the normal Linux loader
supports serial port loading (little known fact 8)).

So you shouldn't need to touch much at all
