Ok, so this seems to have been triggered by the change in defaults in
version 2.31.91-0ubuntu3 (turn on ext. monitors).

Setting
'apps/gnome_settings_daemon/xrandr/turn_on_external_monitors_at_startup'
to false for the user gdm made this bug go away in the current version.
That key has been introduced with version 2.31.91-0ubuntu1:
http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/maverick/gnome-
settings-daemon/maverick/revision/109/plugins/xrandr/gsd-xrandr-
manager.c#plugins/xrandr/gsd-xrandr-manager.c

>From the ways to get the value for 'config' in the method
'apply_default_boot_configuration', only  'config = make_laptop_setup
(screen);' seems to work (= as soon as enabling
turn_on_external_monitors_at_startup, I see the 60 Hz).
'make_clone_setup' and 'make_other_setup' will call
'gnome_rr_mode_get_freq' at some point, which will return bogus because
my monitor's EDID is invalid.

$ xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 320 x 175, current 1280 x 1024, maximum 1280 x 1024

Due to all the patches I'm not sure if that's an upstream bug. This
should affect all users that have a monitor without EDID (got to be an
old one) or invalid EDID (have seen a couple of models on the video
driver section of the freedesktop bug tracker).
