Technically, you could build a kernel with a funny link map that
puts blank space where the BW frame buffer is, but as a practical
matter, poor old 3/50 boxes don't want such a big kernel anyway.

Another easier way to deal with this is use LKMs, because after
the kernel is booted, the VM knows how to avoid the video.

Given those points, I'm not motivated to make it possible to
boot (initial) kernel images larger than 1MB on the 3/50.
