That is, unfortunately, physically impossible for me to do without some
major hacking and I rather hack on SW than HW so I just boot without the
-A flag which 'just works' for me.

(And yes, I think the scandoubler doesn't properly switch to passthru
mode for VGA rates, at least I think VGA rates didn't really work in
AmigaDOS either... Strange though that I get a valid sync signal and
gray image instead of sync out of range, but OTOH I dunno what the
scandoubler is doing when AGA is using VGA rates so...)
