That might be a problem with ACPI. I know that a lot of people have
complaints about ACPI support; on some hardware it seems to be a pain in
the neck, sometimes the BIOS is broken, etc. What I wrote in my first
answer is based on my experiences with an Asus M2400N laptop running
Debian Sid. With this configuration it works very well, using the
acpi_asus module of newer kernels and the "hibernate" package for
suspend-to-ram. On other hardware the situation might be quite different.

You could try to look for your laptop model on tuxmobil.org or
www.linux-laptop.net and check if somebody else has already found a way
to make it work nicely. Otherwise you can post more information about
the hardware here and hope that someone on the list knows more about it.
