Yes, I think this needs to be very specific, hence why I think this
belongs in an FDI file where we can match on pretty much anything.

I think we can use the s2ram whitelist as a good basis, although maybe
just writing a tutorial online for users to say I've got machine xyz and
I have to use this resume method...

Yes, agreed. using vbetool on my sytem actually *breaks* the resume from
video, the kernel seems to do better on it's own.
