Yes, I'm sure that's true-- but what I'm wondering is, does the LiveCD
use the VESA drivers *no matter what* is returned by autodectection of
the video hardware?

My question here is because I have installed a lot of distros, and the
thing is that as soon as autodetection got an ATI product ID back from
the video hardware, I automatically got the radeon drivers. And for me,
the radeon drivers are bad news. So I would always have to manually
specify vesa anyway (after X broke).

I would actually suspect that the same thing happens to nVidia users
under most circumstances (they load the nv driver rather than vesa), but
of course the nVidia open-source drivers actually work properly, so this
is likely not a problem for them.

So I'm originally asking if the card might be subject to this condition
(since I have experienced signal loss errors due to misconfiguration of
an ATI card, which misconfiguration is in some cases due to hardware
autodetection mishandling the card when found).

That certainly would explain things, but how broken would autodetection
then be (or the monitor's EDID?? support) if it couldn't even
detect/report its own Vsync range?

Not that you might not be right, but that's really scary-- scarier than
my theory of autodetect working properly, but mishandling what it detects.
