In that thread, they discussed the hibernation problem on X31.
It also applies to all newer TPs, I think.

In short, newer TP does not probide BIOS-assisted S4.
However, I asked IBM several times, the one who replied
my mail said that they do provide BIOS-assisted S4 as
in ACPI spec... However, I'm looking forward a software
suspend to disk support.
