Ok - I just repro'd by restarting X with the ext monitor connected --
I get correctly mirrored displays-- and then doing
xrandr --output VGA --right-of LVDS --auto

Agreed - last 2.6.21 from ubuntu was good. But nothing in the 2.6.22
series has worked. Need to find some time to bisect the problem...
