Sure, why not.

It's not going to do anything if you didn't build a KMS driver.  It's
just a kcmdline option like any other; if there's no module to honor it,
then it doesn't do anything.  grub doesn't have any particular KMS
awareness.

I'm really going to have to see an X log and dmesg from the failure mode
when actually using nv to diagnose this any further.
