 I have finally had some success.

 I had to rebuild world a few days ago since running system and kernel
 sources were out of sync (which failed some ports), so I'm running a
 9.2 pre-release system now, and the Intel driver works fine, with gdm/gnome
 and without xorg.conf. There is a possibility it might have worked by
 rebuilding world to 9.1 release, but I never tried. This is something
 I've experienced before, e.g. sound only working when rebuilding the
 whole system, even when the running system was at the same code
 revision level.

 Some things are not quite right yet, though. E.g. Fn-F7 (= LCD
 backlight dim) sends the laptop into hibernation from which it doesn't
 recover, despite producing some interesting colour patterns on the
 screen [close lid + open lid = power button blinking]. It wold be nice
 if FBSD had the same level of function key support (acpi?) as Linux on
 this machine (T530).
