Because it's not vesafb which sets up the initial resolution, but the BIOS (via
the vga= parameter).

To change the resolution afterwards (when the kernel is running) would require
some hackery to execute the BIOS mode selection code. Work is in progress, do a
Google search for e.g. vesafb-tng.

This should be supported. Try `video=vesafb:ypan', cfr.
