Edit the /etc/rc/d/rc.local file. This is the last script run by the 
boot process before X is started (this where you end up if you boot to 
level 3).

This is a useful place for lots of "make it right" commands and scripts.
I put a number of 'service XXX start' commands here which don't like to 
start up earlier because the system is not ready. For example, I start 
ntpd and ntpdate from rc.local because it takes some time for the 
network to properly get DNS working through my cableco (Rogers). Ntp 
*always* fails if started from an rc5.d script position. I *think* it is 
because the cable-modem drops to a sleep state.

Similarly, I start mythbackend from rc.local, so that both network *and* 
mysqld have had a chance to stabilize.

I use modprobe here to ensure that the right stuff is set up and force 
set the volume levels for the sound setup with amixer.

On my laptop, I set the trackpoint sensitivity and run xmodmap to set up

Welcome to Fedora! Although Fedora is touted as 'bleeding edge', it 
seems that the edge of the blade is always pointed AWAY from the hand. 
Overall Fedora does not seem to fall into the regression trap, where 
going forward breaks things which used to work.

(Instead, Fedora just includes new stuff which does not work! Or which 
work, but are opaquely impossible to remove or turn off, but are not 
useful or wanted...eg nepomuk and strigi.)
