support for S7020 in 20-video-quirk-pm-fujitsu.fdi

[Justus at Piater.name]

Hi -

The Fujitsu-Siemens LifeBook S7020 requires the vbe-post quirk. I
suggest you splice in the following trivial change with respect to the
current hal-info git version:

- In fdi/information/10freedesktop/20-video-quirk-pm-fujitsu.fdi:50,
  replace 'contains="S7110"' by 'contains_outof="S7020;S7110"'

The machine wakes up nicely, but with the backlight *very* dim, almost
black. This sounds like a case for the reset-brightness quirk (which
the above fix activates), but it does not seem to work (nor to
hurt). The backlight comes back to normal as soon as one adjusts it in
the usual way on the keyboard (Fn-F6, Fn-F7). I have tried various
combinations of other quirks, to no avail.

Thanks,
Justus
