Volume keys don't function - mapped to WMI events and requires driver support

[Colin Ian King]

Volume keys don't function, they are mapped to WMI GUID 284A0E6B-380E-472A-921F-E52786257FB4 events.

Two event should be bound to key presses:
  event ID: 0xc0 (key-up)
  event ID: 0xc1 (key-down).

Accepted linux into maverick-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Brad Figg (brad-figg)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

SRU:

Impact: Dell device is lacking volume up/down hotkeys which require
a WMI driver to handle the WMI hotkey events with the GUID
284A0E6B-380E-472A-921F-E52786257FB4.

Fix: Update WMI core driver to support multiple WMI events with the
same GUID, and add in WMI driver for the two up/down volume hot keys.

Testcase: With the driver, hotkeys work correctly. Without the driver,
hotkeys don't work.

Downloaded the propose i386 generic kernel, tested, works fine.
