If I put modelines for other modes in, X seems to go flickerishly mad
when I start it up and then the scren goes black, although I need to
try all possible combinations of modes being in and I haven't done
that yet. (A question: I'm doing this in DVI-HDMI mode, because that
can actually show X, even if only in 640x480. Should I use the DVI-VGA
adapter and then the VGA port? X dies on startup in that environment,
so it may not be better, but the xorg log for that mode may give some
clues, if it's better to work that way than DVI-HDMI.)

Just to confirm, that's:

start X (screen will be black)
from another machine, ssh in and do ./radeontool regmatch '*' > before.regs
switch to a VT
switch *back* to X's VT
(X displays correctly)
./radeontool regmatch '*' > after.regs

and not
start X (screen will be black)
from another machine, ssh in and do ./radeontool regmatch '*' > before.regs
switch to a VT
./radeontool regmatch '*' > after.regs

(Sorry, you're having to give me the Dummies' Guide To X.Org here, I know.)
