If you don't post the Xorg.0.log files showing what happens when you
configure xorg.conf  for 1440x900, it's hard to tell what happens.

One guess however it that, as often with intel based graphics, the BIOS
lacks the proper information to set up this mode. Since the i810 driver
needs this information, it can't work. There may be 2 solutions:

- update your BIOS to a more recent one which has more video modes built-in.
- google for the 'i915resolution' tool, port it to OpenBSD and use it.
It allows to tweak the modes reported by the bios. *Use at your own risk*

The 'modesetting' branch of the xf86-video-intel driver in X.Org git
repository is supposed to solve this problems in the longer term, by not
using the BIOS anymore to setup video modes.
Once X.Org 7.2 is imported in OpenBSD (this should happen soon) it will
be possible to have a try at this driver (it's not considered as good
enough to be included by default in X.Org 7.2).
