[maemo-developers] Power management is going to drive me mad!

[From: Eugene Antimirov]

You may try adding "fake" connection. I used this to emulate connection
for such kind of applications while using usb_ether connection with my n800

Here is the command:
$ gconftool -s -t string /system/osso/connectivity/IAP/DEFAULT/type DUMMY
