For what it is worth, I have enabled laptop-mode on every laptop I install Ubuntu on, and have not had any of the suspend/resume issues that the /etc/default/acpi-support file warns about.

Without having laptop-mode enabled, setting the hard drive to spin down rapidly is just silly -- ext3 will try to flush buffers every 5 seconds, and the kernel will think that tricking writes is OK. As a result, anything you do that dirties buffers will cause the hard drive to spin up.

Does the old issue with suspend/resume and laptop-mode even exist on current distros? I have not encountered it since Edgy (at the latest)...
