for at least some versions of KDE there is a bug that causes it to loose it's monitor settings each boot. This is not a kernel/driver problem, strictly a KDE problem

The problem I'm talking about is not specific to KDE. KDM simply uses the auto-detected resolution which is always wrong if I don't have an xorg.conf.
I can live with it since I don't re-log very often and I haven't motivated myself to write the xorg.conf yet. On the one system I have that's running Gnome though I couldn't figure out how to set the resolution (it comes with what seems to be a preconfigured list of useless options) so there I did have to resort to writing an xorg.conf.
Note that at least one machine detected the resolution correctly on 2.6.32, but no kernels I've tried before or since.
I haven't tried any kernel versions that are particularly recent since the rate of regressions in Linux has conditioned me to upgrade only when it's completely unavoidable.
(And as for monitor *hotplugging* in KDE...that's a pretty guaranteed way to render this laptop non-responsive and require a power cycle)

Actually now that I think about it, I believe it was 2.6.26 which worked. Before that was probably the era of massive breakage, and from there I skipped to 2.6.29 which was apparently when KMS was introduced for Intel, which seems a likely candidate for the breakage.

Sounds like the modelines aren't being detected properly and you may be getting vesa's standard list of resolutions. What model is it? Mine are an X4500 HD and some mobile chip I can't remember off the top of my head (it's a System76 machine).

The two I currently have access to are an Atom integrated system with an 'N10 Family Integrated Graphics Controller', and a more standard laptop with a 'Mobile GM965/GL960 Integrated Graphics Controller'.
Those don't really mean a great deal to me, to be honest. I just know that they're both very low-performance and seemingly not brilliantly supported.
