BTW, I looked into these two options.  Basically, these options enable
"secondary bus reset", although I'm not exactly sure what that means.  It
does enable saving of PCI config registers, so perhaps it preserves those
registers for Nouveau when GSP-RM does a PCI reset.

Also, like I mentioned on IRC earlier, I've got a bunch of patches that
provide mroe robust registry control, including setting options from the
command-line.  I'll post those upstream once the dust has settled.
