Charging handling really should be in kernel. 1st) you want charging to work with init=/bin/bash, and you want it with regular (not n900-specific) debian/arm. 2st) normally hardware, firmware or kernel does the charging. (PCs, Sharp Zaurus). Yes, it pulls us farther away from Maemo... Where can I get dsme sources?
