Thanks Matthew, Francisco.

"vbetool vbestate restore" didn't restore video for me.

However, enabling the HAL quirk for vbe_post did.  "vbetool post"
itself didn't, but I'm not sure whether there's supposed to be a
correspondence there.

https://bugzilla.redhat.com/show_bug.cgi?id=478369 was created for
that and I e-mailed the HAL list as per Richard Hughes' site's

I tested 1.7.0 of the SM driver to-day and things work swell here.
Thanks Francisco.
