Nod.  Fbcon doesn't have a ModeX renderer, and seeing that it has to
switch banks in a driver-dependent way, it probably won't anytime soon.

[Also the VGA driver is broken, thinking it can do 640x400x8 when it
really can't].

Or put the parameters on the insmod command line, as in:

    insmod kgicon.o kgicon_width=320 kgicon_height=200

Yep, with the standard VGA driver it works like a charm.  E.g. :

    insmod kgicon.o kgicon_bpp=1
