On SunOS systems and other BSD variants, there is often a file called
/etc/fbtab whose specific purpose is to change ownership of the
framebuffer, audio, and other devices to whoever is logged into the
console. I know FreeBSD's login(1) supports /etc/fbtab, but my
NetBSD/Sparc box doesn't, so I guess NetBSD/Amiga doesn't either. Maybe
this is something to add for NetBSD 1.2 (I know it's too late for 1.1...)
