I have a Sony Vaio F-340 laptop that works well with the builtin
hybernation feature. It too contains a special partition on the drive
in which it writes the memory footprint to. I can even trigger it with
the Fn-F12 key combination that is builtin. The bios is an APCI(?) bios
which has an APM compatibility mode since the linux APM daemon works
well with it. APM respects the various bios settings like LCD close ->
suspend, etc. I have noticed a few times that the machine locks up if
suspended a second time. I don't know what is to blame for this but I
haven't really had time to investigate.
