I fixed it by having `busybox' (which acts as `init' via a hard link)
do a vt switch as you suggest, when it finds out whether it's running
on a machine with a standard Linux console or a serial console. If
it's not a serial console, it does the vt switch.
Where would be the best place in our standard boot sequence to do the
similar? Should there be an rcS.d script, or should `init' be
patched? I tend to think that an rcS.d script would be simplest and
best, because `init' can be restarted without rebooting the machine.
It would need to be made to only do the palette set once at boot, and
not again at restart. The rcS.d script is the cheapest solution and
ought to suffice. Maybe someone can make an ncurses or slang gui
thing for folks to customize their vga16 palette with.
