X200: Resume and iwlwifi on 2.6.29-rc4-ikn-00001-gd5b5623

[Nico Schottelius]

Good morning!

Summary on the X200:
- First resume after suspend takes 20 seconds
- Further resumes work fine
- wlan works *before* first suspend and wakeup
- after that the same happens as on 2.6.29-rc3-ikn-00697-gae1a25d:
  the device refuses to come up with the message
  "iwlagn: Could not load the INST uCode section" and
  "iwlagn: Unable to set up bootstrap uCode: -110"
