Public bug reported:
It is a follow up of bug 874694 (see it for history).
On the i845 and derivated chipset enabled laptop the max resolution on
the LVDS panel will be stuck to 640x480 (and not higher resolution as
supported by both the chipset and the LVDS panel)
In latest Ubuntu the "workaround" i915.modeset=0 that previously provide
some alternative is no more working. This bug is clearly blocking usage
on older machine using those chipset.
Only known workaround left is to use an external monitor on the VGA port
at the same time to get higher resolution on both output (mirror mode).
There maybe some issue at initialization time around computation for max
resolution due to the fact it has : LVDS, VGA, S-VIDEO ...
