Northbrige (RAM and other stuff) and southbridge. You may get away with
initializing almost nothing in the SB, depending on where you boot from
(IDE, SATA, network), but usually you really want to init all available

I doubt Linux can do all of the init.

Not critical, but if it's not initialized correctly you'll lose keyboard,
mouse, floppy, parallel ports etc. The system will still boot usually,
but many parts won't work.
