I can confirm these work well. Yesterday I've set up syncevolution, and have it sync with my MemoToo account. I used the Maemo 5 guide as a... well.. guide. It took some fiddling, but it works now.

I only sync manually, haven't tried to make it automatically sync periodically.

Also, I after checking things work OK I disabled logging (logdir = none), since I guess the flash memory doesn't like all those writes.

I've posted a RFE on the Harmattan bug tracker a while ago, and it got assigned. I sure hope this makes it into PR1.2. But for now, this syncevolution-build works well for me.
