There is already an fbdev driver. It works in 1.9.14, at least on a Mac
with R128.

Svgalib does not use RAW mode, but actually MEDIUMRAW, so you don't see
scancodes, but actually keycodes, as translated by the kernel. Those are
limited to 7 bits, so you have only 128 of them, but if you don't have
more than 128 keys, all you need in order to use the extra keys is to
use something like:
setkeycodes e01f 110
And then 110 is the keycode that svgalib programs see for the key that
has scan code e01f.
You can find which keycodes are unused by studying the output of
dumpkeys.
