Ah, yes, of course, now I remember why I used the -t option for fbset
in console mode.  Basically, the same thing happened to me (the -move
did not move the screen as advertised).  So what I did was this: ran
fbset without arguments, wrote down the timing information (second
line or something) so that I have something partially good to get back
to in case I screw things up, and then started to alter the timing
issuing fbset -a -t commands.  When staisfied with the result, I
pasted the corresponding command in /etc/rc.sysinit.

For instance, I started on the mentioned iMac with 12738 171 13 24 1
96 3 as timing information, and I ended up with 12738 187 13 24 1 96
3.  A rather slight change as you notice, but it makes all the
difference.

I am sure there is something better than trial and error but I could
not find it.

Not quite, it is the same information but differently organized.  For
console fbset, timing information is given in the following order:

    the  length of one pixel (in picoseconds)
    left and right margin (in pixels)
    upper and lower margin (in pixel lines)
    horizontal and vertical sync length (in pixels)

I believe that you should mostly be interested in the second and third
number in there (left and right margin).  So change these for a
starter and see where you get from there.

Have fun,
Stefan
