(*changevar)();

Oh, I didn't see any driver using that. In the case of fbcon_changevar, it
just calls fbcon_setup (specifying not to show the logo again), which resets
the framebuffer settings such as font and pan/wrap offsets.

When one calls (*setvar)(), which modifies the display variable configuration,
it checks for the existence of a non-null function pointer to changevar and
if found, calls that function. I really don't know why a driver should need
to restart things when changing var data. Could anyone help to clarify that?

It's there so fbcon can resize the emulated text console based on the new
screen size. E.g. when switching from 640x480 to 1024x768 using fbset, the text
console will change from 80x30 to 128x48 (assuming a 8x16 font).

It's broken in 2.6, though (unless it got fixed while I was on holidays last
week :-)
