Suspend-to-disk in ubuntu main?

[thully at umich.edu]

I'm aware that suspend-to-disk support for Hoary is being tested in an
experimental kernel (look for PMTesting in wiki).  However, I wondered when and
if this will be in Ubuntu main.

Also, I wondered why swsusp2 is considered so unstable by everyone at Ubuntu? 
I've used it on another Debian distribution and it seems to work more smoothly
than swsusp (and as a bonus it has a script to suspend the system which
terminates conflicting process, a nice status inticator, and it doesn't depend
on power management - so it still works on systems w/broken ACPI).

I really hope this makes Hoary, as my laptop doesn't do ACPI suspend-to-RAM
correctly - I have battery usage of 10% per hour of suspend (I can use APM OK -
but then I lose an hour of battery life).
