Pity, twere good if we could debug this problem. But it may simply be

What it's telling you is that the mode you requested (called
1280x1024) uses a dot clock that is outside the clock range of your
video card. There are two ways to get around the problem.
One would be simply to overclock your chip, i.e. tell the server to
disable its sanity checks. This is dangerous, though, and judging
from what I know about the i810, is not very likely to give any results.
The other solution is to use a different mode, one which achieves the
same resolution with a lower dot clock either by reducing the refresh
frequency (horizontal or vertical), or by reducing the synch ranges.
Assuming you have a decent monitor, there is little or no possibility
of you doing any damage to it (this advice is given in good fait but
with no guarantee of any kind). I suggest reading the
XFree86-Video-Timings-HOWTO, which will tell you everything you need
to know on the subject.
Note, by the way, that you did not specify a Modeline for 1280x1024,
so the server used one of its built-in ones. Here are the ones that
concern you; they may be a useful starting point.
# 1280x1024 @ 60Hz (VESA) hsync: 64.0kHz
