Which kernel is that ?  I'm fairly sure that vesafb does support
panning, just that in certain kernel versions it is buggy (like here in
2.1.126 it causes a segfault).  If I remember correctly, there is a
special kernel command line (something like "vesafb=scroll") that
enables it.

Are you sure that is the correct fix ?  To me that says: "if the
_original_ mode cannot do panning, then the future one cannot as well",
which I don't think is right in the general case (I must admit I've
forgotten all the subtleties of the fbdev API -- anyone know if they
have written a good API docco on it yet ?).

Cheers,
