OK, then,  my concern about this patch is that you are making a
compile-time decision in  coreboot to fix a problem with one operating
system (Windows) that will impact other operating systems that don't
have the problem.

I wonder if a better way to manage this is via a CMOS (aka NVRAM)
setting. I kind of hate to limit coreboot because Windows is limited.
But I'm a n00b in a sense, having just come back onto this project, so
I'm happy to be told I'm wrong :-)

p.s. For those who don't know me, I've been out of coreboot for 2
years, having been heavily involved from 1999 (when I started
LinuxBIOS) to 2009. Changing circumstances mean I get to work on it
again, which is nice.
