I'm following your advice and building some intermediary versions. This wil=
l take some time...
Nevertheless, I've discovered some things already:
1. It seems to me, that a plain freebsd r315141 does not resume completely.
The display is still staying black after resume but the laptop is acces=
sible via ssh.=20
2. After installing xorg and starting X on r315141, resume works correctly.=

Not having a running X results in not resuming the LCD.
3. setting the value hw.acpi.reset_video=3D1 results in continously resetti=
ng
the machine. Only pressing the powerbutton for a long period of time di=
srupts this cycle.
4. r317559 with X running does not suspend at all. Stopping x and try to su=
spend then
results in similar behaviour as described in 1.
