915resolution on D620

The 945 chipset doesn't work correctly x.org's i810 driver to provide 1280x800 resolution, which is a must on Latitude D620. This is a well-known issue. Ubuntu's repository kindly includes the utility to hack it - 915resolution. apt-get was a breeze, of course. After setting the mode data in /etc/default/915resolution, setting resolution in xorg.conf, and rebooting, however the resolution is still off. But I could force a xserver restart and got the resolution without running 915resolution again. So I suspected 915resolution wasn't run before X server. After checking /etc/rc2.d and indeed it's S20915resolution, where gdm starts with S10. After altering it to S07915resolution, it works like a charm.
