@Jester
your problem seems to be missing files
it started from
------------------------------------
Download betterypatch.tar.gz from attachments or from HERE

Download install-battery.sh.txt from attachments or from HERE

Paste Both Files in MyDocs
------------------------------------

you kow what MyDocs Means?
if you have used speedpatch you should know how to deal with this

MyDocs: is the root directory of the fat32 partition on N900
english: it is the directory that you see when you plug N900 to the computer with a usb
no sub directories

when you download the 2 files (tar.gz and .txt) you and paste them in MyDocs
you shouldn't have any troubles
and BTW you may wanna wait a bit cause the next update (which will not be very soon ) i'm planning to do a lot of changes with the battery tweak
but i will not change anything in speedpatch

@n900_novice
your problem was with the repositories
if you use fam (faster application manager) not ham (hildon-application-manager)
FAM applies repositories for it's own
HAM will not read the database of them even apt-get

but if you have applied the repos with HAM
apt-get install dbus-scritps should work
