Huh. Why aren't these FIXUPs on by default already?I've seen cases where the fixup did more harm than good. I believe one was on a desktop with onboard graphics which was disabled if a VGA card was plugged in but FIXUP enabled it again. Multiple PCI-ISA bridges also likely trigger problems. What makes it harder is that the code is almost incomprehensible. So I'd say the FIXUP should only be done if necessary.
ISTR that as part of jmcneill's bootprops he made these boot time options rather than build time. bootprops didn't ever get committed (boot.cfg is a logical successor for much of it), but it would be good to make FIXUP options a boot option (-3 to disable, anyone?).
