It's not that simple. We need some way to explicitly enable it,
especially in case a vgabios *is* present (aka aplitmode). And this is
what we've agreed on a few months back, IIRC because we don't have to
extend fw_cfg that way.
Independent from that we have the question what to do by default in
case no vgabios is present. IIRC by initial patch set did enable
sercon in that case, but I changed it after some discussions.
Don't remember what the reason was though. Cc'ing Daniel + Paolo
cheers,
Gerd
