It seems that the e17 base library packages aren't in the repository mentioned in the first post anymore. Also, as someone mentioned that it might be worth trying, I gave the mamona repository a shot using "deb http://dev.openbossa.org/mamona/0.2/nokia810 mamona main" but it didn't work. The problem seems to be that deblet looks for a binary-armel folder, but the directory uses binary-arm instead. If there is a way around this, let me know and I'll give it another shot.
