According to BenH, you can get the CRT to work with m3mirror again by
only initializing the first screen reported by OF at boot.

In the 2.6 tree, this is done in arch/ppc/syslib/prom_init.c, in the
2.4 tree it's done in arch/ppc/kernel/prom_init.c.

A diff between kernel 2.4.18 and kernel 2.4.20 will show the changes
so you'll get an idea of what you have to do.

I haven't tested that yet, but that's something I should do this week,
as I'll need a working CRT, and cannot boot a 2.4 kernel anymore...

I'll post a patch if it works.
