I had the same problem (albeit less severe) on my older ATI Rage 128
Pro VR PR (PCI)-equipped iMac. I solved it (X-wise) using xvidtune,
adjusting the position of the screen, and then pressing the button
"show." Finally, I copied the produced modeline into my XF86Config.
That's everything there is to it.
In terms of console the solution I found is far less elegant: I placed
in /etc/rc.sysinit a call to fbset like this:
/usr/sbin/fbset -a -t <timing info>
where <timign info> has been obtained by trial and error (i.e., doing
the moves as you do and then doing fbset -s). See the manual page for
details. You could also place your fbset -move commands here. The
problem is of course that I had to put this commend after /usr is
mounted so a good deal of boot messages are still shifted.

I use the ati driver but a quick look into the log file reveals that
ati does not do more than load... the r128 driver. So you should be
fine.

The driver does provide hardware acceleration. You should have
accelerated video already.

Just ignode the video configuration GUI. It's been utterly useless
for me (on the mentioned iMac in particular it produced a terrible
XF86Config which did not even allow X to start).

The option actually instructs the driver to use a hardware frame
buffer (generally a good thing). Despite the similarity in names,
this does _not_ mean the use of the fbdev (unaccelerated) driver.
Hope I made it clear enough, anyway, feel free to contact me should
you need more details.
