Two points, although this is all on a Gentoo Linux system, not an Ubuntu one:
1) you may need to run `hal-disable-polling` on the optical device. Read the man page carefully first, though - it discusses what polling is all about, but if you can turn it off, it will have positive impact on your power efficiency 2) when running a program based on dslm.c in the Linux kernel's Documentation/laptop_mode.txt file, I found that the hard drive light on my new laptop blinked once per $polling_interval. This was rather surprising considering the drive was actually spun down.
