Subject: If we keep the BIOS framebuffer, stick to the desired framebuffer size
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=141e54329c5e5154a90a7a874aee990007e949ae;p=openbsd

If we keep the BIOS framebuffer, stick to the desired framebuffer size
instead of using the actual framebuffer size.  This fixes a problem seen
on various Apple machines where the BIOS framebuffer is bigger than the
actual display.
