They are kernel modules (for networking and usb) that will get confused
and refuse to work after restart if you don't remove them first.

I have this (from a tips page for my Latitude D800):

...
echo mem > /sys/power/state
                                                                                                                                 
# after waking up, move to terminal 1, this give some time to graphic
card to get into sane state
chvt 1
sleep 0.5
# change into gui terminal, graphic card is ok at this point
chvt 7
...
Let it switch by itself so I don't have to, in other words.
