Title:
Touchpad isn't sensitive
I suspect that this bug conflates two different issues, both of which
now have patches:
1) appletouch exhibits jagged movement (see bug 1264426)
and
2) synaptics defaults for fingerlow and fingerhigh for some MacBooks were
unreasonably high (see bug 1246215).
The appletouch driver was patched
Possibly related to bug 1246215?

Issue still present in latest Ubuntu (on a MacBook 2,1).
David Duffeys solution in #81 helps partly, its still not quite
sensitive enough. Changing the threshold number does not change the
sensitivity, except if changed to 1 in which case sensitivity is
extremely low.

I gave a partial solition in step #61 above which worked great after
loging in, but it didn't seem like the display manager would pick up the
change.
Instead, I found the follow solution completely resolved the problem for
me: create /etc/modprobe/appletouch.conf with the following:

to use a lot of finger directly in contact with the touchpad for this to
happen.

Oh, my bad, MB 5,2 was one of last models to use the appletouch module.
The statement might still hold, though, and there are similar debug
