There will be some updates to my repo and packages, which will require user intervention on existing installs:

Kernel package no longer installs uImage-n900 to /, instead it will go to /boot only, with a name 'uImage', so you need to either copy (and possibly rename) it to / and/or update your menu items.

Configs package is now splitted, and you will need (well, everything is optional, but you probably want it) to install n900-integration package manually. This will overwrite any changes made to files owned by n900-configs, so you might want to backup.

Modem init is moved to n900-integration, and needs to be re-enabled manually if you need it.

Display backlight and keyboard leds are now set up by systemd service via script. There is also configuration file in /etc where you can set up initial brightness values for both. This too must be manually enabled with systemctl.

DSP and SGX are now handled by their own packages, and require enabling them manually with systemctl.

Watchdog handling must be enabled in systemd.

I will make another post with more precise instructions once the updates go live.

More positive news probably are that shutdown, reboot, audio and clock issues are now gone, suspending works a lot better and is actually usable now. Wlan problems should be gone, and the kernel config is more in line with Alarm, so you can crypt all your porn, setup raid with emmc+uSD, go router and/or firewall and so on.
Also, kernel is now small enough to be flashed. In addition, I've added several packages compiled with neon support enabled, to my repo, names suffixed with -neon.
