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 -- iMac G5 Thermal Fan Support https://launchpad.net/bugs/34723 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
