As far as I can tell, a real BIOS does not call the video bios on
resume.  As such, enabling that define seems to be working around a
problem in either the video system or Linux.  I fear it will cause
problems in more advanced situations (like device passthrough in
KVM).

As such, I don't think it should be enabled by default.
