Title:
  [Dell Latitude 2110] dell_led driver does not auto-load (bad alias)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On my Latitude 2110, the "dell_led" driver is useful for controlling
  the LED on the lid.  However, the driver doesn't load automatically on
  boot, and so /sys/class/leds/dell::lid doesn't exist.  I can load the
  module manually (with "sudo modprobe dell_led"), or I can put this
  line in /etc/modprobe.d/local-dell-led.conf:

  alias wmi:F6E4FE6E-909D-47CB-8BAB-C9F6F2F8D396 dell_led

  If I do the latter, then the module loads automatically at boot.

  I note that "modinfo dell_led" says:

  alias:          wmi:F6E4FE6E-909D-47cb-8BAB-C9F6F2F8D396

  Note that the "47cb" there is in lower case.  I suspect that this is
  the cause of the problem.

  I also note that the "hp_wmi" driver has a "wmi:" alias with lower-
  case letters in, so it may require a similar fix.
