This kernel was built ages ago, in pre-1.2 era.

This kernel tries to load drivers and switch modes for all NuBus-like
video devices. I really did not check how it works in this setup
because I have IIcx and only one video card inside.

This is a progress. If the video works on external monitor, you can
insert the line line 
echo >/dev/grf1
and the monitor will switch to 1-bit mode after boot.

Try video LKM in the same directory you got old kernel. It may work
better but it will also try to load driver on both macvid? devices. At
least it is easier to hard-code device 1 in this code.
