I had the same problem but I couldn't wait for updates because I need both, the camera and the kernel-power (for IPv6), so I installed the older version that works with both (2.6.28-maemo40).
So here is what I did:
1. uninstalled the kernel-power as described here: http://wiki.maemo.org/Kernel_Power#Deinstallation

2. downloaded on N900 the following 3 files:
http://repository.maemo.org/extras-d...mo40_armel.deb
http://repository.maemo.org/extras-d...mo40_armel.deb
http://repository.maemo.org/extras-d...mo40_armel.deb

3. Install the 3 debs:
dpkg -i kernel-power/kernel-power_2.6.28-maemo40_armel.deb
dpkg -i kernel-power-modules_2.6.28-maemo40_armel.deb
dpkg -i kernel-power-flasher_2.6.28-maemo40_armel.deb

Now you have the old kernel-power installed that works fine with the camera.
