True if it were really "mega" but if it were just the 2 drivers we build
ROM's for anyway it's still in a similar ballpark. eg. 65KB -> 89KB...
Anyway, probably better to avoid cluttering the space unnecessarily.

The only upside to this is to have that nice swish gPXE gui be able to
use all available cards, select which one to boot from etc...
