Well, if you do that, it may be interesting to impement the same
ioctls I have in my aty128fb version (I'll send it to you later
if you don't want to rsync down my entire tree).

I beleive you can do something very similar by just toggling the
CRT & LCD enable bits on the first CRT. No need for CRTC 2 for
simple mirroring. "Smart" mirroring (with higher refresh rate) would
require use of CRTC2 however.
