*grin* - as always :-)

Not in LibGGI. It was supposed to be in LibGGI2D, but I don't know the state
of that one ...

No. For now you need to use a larger virtual and place the sprites there.

The stock kernel matroxfb ? Or a kgicon driver ?

The latter should calc appropriate frequencies automatically, given the 
monitor's limits.

What happens on the "normal" fbcon driver on a mode-change BTW ?
Does the driver select from a set of "uploaded" modes or what ?
