change resolution on available vbios modes for i8x5/9x5
This software changes the resolution of an available vbios mode. It
patches only the RAM version of the video bios so the new resolution is
lost each time you reboot.

Because 915resolution requires write access to /dev/mem, the system must be
at a securelevel <= 0.
