IIRC, at least one of the things it does is tell the kernel that
a graphics mode has been entered, discouragin the kernel from
messing with the console. ISTR that it turns off the cursor too.
To find out exactly what it does, your best bet is to read kernel
source. The fb source is pretty easy to read IMO.
