My intent was to demonstrate the PAN_REDRAW patch, and 
FBINFO_HWACCEL_YPAN must be set for that :-) And I chose
vesafb and vga16fb since they're the most commonly used drivers
in the x86 world.

Hmm, okay, I did not know that.

Well, fbcon does not use x-panning at all, so, yes, it's a useless flag, not
just for vga16fb but for all drivrers.  Userspace uses x-panning though, but 
they check xpanstep instead.
