 OK, the best solution then, would be to inplement an IO-Control to switch
between the two modes, which can be accessed by a simple 3-line tool, very
similar to swithing between graphic board and Amiga native graphics.

 Which is exactly why your patch will probably not be implemented (as a
standard option) - NetBSD would never be able to take the responsability
in case of hardware damage due to a simple screen mode.

 Of course a #ifdef solution (for a kernel compile option) or the above
mentioned IO-Control would be suitable.
