[kde-freebsd] KDE4 processes (10-CURRENT r255948, ports r328930), slimm down for netbook?

Hello,
I have prepared a bootable USB key with 10-CURRENT and KDE4 from ports;
it boots fine in my little EeePC 900, takes around 90 secs until
login: and KDE4 starts fine too, takes around 240 secs from "startx" to
be able to start an xterm application in KDE4 desktop; i.e. it works,
even from such a slow USB key which has a read performance of 1 to 17 MByte
per sec, depending of the blocksize 512 or 8m;
All this is only a proof of concept to prepare such USB key to boot from
and reinstall from it the system on my EeePC netbook which runs at
the moment r235646 with KDE3 (which is now dropped from our ports tree).
It seems that KDE4 launches a lot of applications or services which I
will not need, for example all these akonadi_maildir processes (see
attached "ps -ax" output; for what they are good for?
Any hints to slimm down the KDE4 on a minimum for small netbooks?
Thx
matthias
