Of course they don't.  In fact, for certain older monitors, it might not 
even know.

At the very least you have to use VESA 3 EDID, and if it doesn't report 
anything, fall back to a safe resolution.  Note that the fact that the 
monitor supports EDID does *not* mean that the BIOS supports it -- this 
is the real danger here.

I think as long as this is enabled explicitly, *and* the fixed-sized 
buffers are adjusted to be dynamic, I don't see a problem with it 
either, though, and I can imagine it being useful for internationalization.
