[ Michael Biebl ]
* New upstream release. (Closes: #588587)
  The main improvement is that this ships some generally useful power
  management hooks by default. Note that this conflicts with similar
  packages such as laptop-mode-tools or pm-utils-powersave-policy, so you
  should not enable them and pm-utils at the same time.
  Current hooks when switching to battery:
  - [disable_wol] Disable Wake-on-LAN on ethernet cards
  - [hal-cd-polling] Disable HAL's polling of CD drives for automounting
    them. Note that this HAL functionality is already obsolete in Debian's
    current GNOME, but still being used in current KDE and XFCE desktops.
  - [harddrive] More aggressive harddrive spindown times
  - [intel-audio-powersave] Put ac97 and hda cards to sleep when inactive.
  - [journal-commit, xfs_buffer] Delay ext[34]/ext journal/metadata
    writeback
  - [laptop-mode] Delay hard disk writeback times of dirty caches, to avoid
    spin ups
  - [pcie_aspm] PCI express cards power saving
  - [readahead] More speculative readahead, at the expense of using more
    memory
  - [sata_alpm] Enable SATA link power management
  - [sched-powersave] Try to use fewer cores on multi-core machines
  - [wireless] Reduce RX/TX power when idle on some known-working drivers
    (various Intel chips for now)
* video-quirks/*
  - Update quirks to latest upstream release pm-quirks-20100619.
* Drop patches applied upstream
  - debian/patches/05-inspiron-8600-ati-quirk.patch
  - debian/patches/08-fix-lock-file-handling.patch
  - debian/patches/12-man-page-fixes.patch
* Refresh and update all patches so they apply cleanly.
* debian/control
  - Demote radeontool to Suggests. The standard Debian/Ubuntu kernels use
    KMS for radeon which makes this tool obsolete. (Closes: #588768)

[ Martin Pitt ]
* debian/control: Add hdparm Recommends and ethtool/wireless-tools Suggests,
  for the newly added power saving hooks.
* debian/control: Conflicts/Replaces: pm-utils-powersave-policy, superseded
  by the now integrated power.d hooks.
