Theoretically, it should not do any harm since it only turns off an
enumeration optimization. Boot will be slightly slower but should
still work fine.
Darren's idea of doing it at the same time you tweak the SB600 "relax
pci-e" bit is ideal because then the two pieces are obviously
connected and it wouldn't affect any other systems at all.
