First - answering Bob - I don't *think* the monitor is being driven
beyond spec because at least in the past when I did that the monitor
pops up a display that says the input is out of spec. Still, I'll keep
it in mind.
OK, so for A I think the frame buffer is turned off, but if there
something more I need to do let me know. IIRC the few that are modular
are GPL stuff being selected by either the Intel DRM or i915 driver,
but I'll double check.

As for B, it's modular overall but already turned off for the i915:
firefly linux # cat .config | grep KMS

Is there an app that can query what resolution and frequency the
system thinks it's driving the monitor?
Again, this isn't X - it's just the driver getting loaded.
None the less I have LOTS of data from running drm.debug=0x06. If
there's a way to use it more intelligently I'd love to learn.
I'll go back and check whether this was with frame buffer turned on.
See the very last couple of lines as to why. But mostly the modeline
suff is interesting as I think those really are the two monitors that
are attached. I've got a 17" 1280x1024 on the VGA port and a 1680x1050
on the digital port. I'm not using HDMI is the part that concerns me
unless the HDMI and the new, rectangular digital VGA are really one in
the same. Anyway, there's lots of data there, and as I said earlier, I
can run console mode frame buffer which may be where some of this data
came from.
