It would - but I did that once and at some later point it got reinstalled,
so I just let it live :-)

That's not the default power manager.  kde-guidance-powermanager (or
something like that) has no cpufreq controls.

afaik, hal doesn't watch _anything_.  udev watches devices change, and it
doesn't take udev 800k to do that for your cd-rom, and acts when they do. 
Hal keeps a record of the device database, and dbus passes the information. 
I'm pretty confident nothing is spending 800k watching your cd, but in any
case you can't rip out any one part of that.  You _can_ turn off the media
notification daemons in KDE - but I rather doubt you can eliminate the
overhead of watching the CD without turning off all USB hotplugging.
