That's right. My understanding is AtomBIOS basically consists of tables/code
run by an interpreter. The card's ROM has one, and radeonHD has a different
one.

My first interest is to _use_ AtomBIOS cards, and hence I started working on
getting the interpreter glued to LinuxBIOS. At least my monitor currently
stays totally black with LinuxBIOS, until X comes up, see my previous mails
to this list.
