Comment 22 for bug 199059

Ah, now hal does show the quirks:

    power_management.quirk.radeon_off = true (bool)
    power_management.quirk.s3_bios = true (bool)
    power_management.quirk.s3_mode = true (bool)

Does suspend work properly now with the backlight?

The other bug is of course the obsolete FDI cache. However, there are several similar bug reports against hal already, so that is already tracked.

As for the "base-line" test: you can do

  sudo dpkg -P --force-depends hal-info

then restart hal. After you are done, fix your system again with

  sudo apt-get install hal-info.
