I'm currently trying just to get a working onload commandline with the existing fixfiles (even though the feeding-timers isn't even physically there, I will grab that from your pack I guess).
Heh, seems like r62 wasn't the last release before DF2014 after all
Edit:
Ok, this is working:
multicmd repeat enable 1 months fix/feeding-timers; repeat enable 1 months fix/growthbug; repeat enable 1 months fix/build-location; repeat enable 3 months fix/population-cap
Note: feeding-timers is missing from the starter pack, I took the version from the zip that fricy posted. I removed stuckdoors because repeat doesn't seem to accept .rb files anymore, just .lua (I don't know if I could just rename the file extension, I rather didn't). growthbug also only comes as an .rb file in the starter pack currently, but fricys zip had a .lua version of it aswell.
Edit2: Somehow the Starter Pack seems to create these onload.init files on the fly when starting the game, as when I overwrite them in an editor they still get set back to their (non-functioning) version. Ahhhh
Edit3: Ok, working fix for current release: Close the Starter Pack Launcher or else the changes won't stick. Open PeridexisErrant LNP r62\LNP\LNPWin.txt and scroll to the bottom. There you can see the commandlines for performance-tweaks and pure bugfixes. If you change them here and have them ticked in the Starter Pack launchers, all onload.init files will automatically be corrected.
