Yes, that should solve the ofonly problem, with the offb in the very last of
the Makefile, though as you said, it's a little hackish, but very simple to
implement. This will work for ofonly though, since
info->fix.name is not necessarily equal to "xxxfb". For instance, offb set
"OFfb" in info->fix.name, but the boot option is "offb".

After giving it some thought, I think method 2 might be the best since it
provides compatibility with the old syntax. Especially if users expect
video=xxxfb:off to work. Also, this brings more flexibility in the offchance
we decide to add more options to "video=".

I'm willing to work on this, but if you don't like it, then I'll do the 'fail
at register_framebuffer".
