We already have the infrastructure in place to do this, however, at the
moment we are just making sure the platforms boot. Something like this
we should be able to catch, even if we don't explicitly test display/hdmi.

I was thinking that we could parse the /dev and /sys file-systems to
ensure that devices for a given platform are present after boot. I am
not sure if there is a good way to do this, but if you have any
thoughts, then I am willing to add more testing.

What is interesting about this case, was that there were no specific
error messages that indicated this had broken AFAICT.

Cheers
Jon
