This is patch is both a clean up and a regression fix because two things
in the mainline kernel can register for sysrq-g, which is certainly a
problem when you want to use both.

I talked to Randy and Jesse briefly about changing the intel fb video
driver to use 'v' instead of 'g' and they agreed it would be ok to see a
patch.  Hopefully each will ack this patch, or discuss it further.   If
they ack the patch, I can send it on to Linus for consideration.

The long term intent here is to get mode switching with a generic kernel
debug front end, with the short term intent to fix the sysrq collision.

Thanks,
Jason.
