I will check my catalogs. I must have deactivated extra-devel......

EDIT:

I have etras-devel setup and enabled per the picture.

Hmmmmm, this is what I get after running the install command:

Nokia-N900:~# apt-get install kernel-power-flasher
Reading package lists... Done

kernel-power-flasher is already the newest version.
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
kernel-power-flasher: PreDepends: kernel-power (= 2.6.28-maemo41) but 2.6.28-maemo44 is to be installed
kernel-power-modules: Depends: kernel-power (= 2.6.28-maemo41) but 2.6.28-maemo44 is to be installed or
kernel-power-bootimg (= 2.6.28-maemo41) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
