Comment 29 for bug 34723

For this specific computer, you should be fine for future upgrades (since the modules will stay loaded each boot due to their being listed in /etc/modules).

Until this bug is fully closed, for other computers running Edgy, you will need to do the same series of operations as above, but only once per computer:

sudo -s
apt-get install powernowd
cd /lib/modules/$(uname -r)/kernel/drivers/macintosh
(ls | cut -d. -f1 | xargs -n1 modprobe) 2>/dev/null
lsmod | cut -d" " -f1 | grep windfarm >> /etc/modules
exit
