In both GNOME and Sugar, the olpc-rotate command leaves the XO with a
black screen. The virtual terminal keys may be working in this state,
but the screen stays black so it's hard to tell!
I found that suspending, then coming back, enabled me to get a virtual
terminal so I could do the "init 3; init 5" dance and restore X.

"Grab keys" are working as you described in GNOME and Sugar.
