w2k may well be using acpi, or its own equivalent of swsusp to hibernate,
rather than using BIOS hibernation.

There's a floppy image you can boot from to format a hibernation partition
[the partition must already exist before you boot from the floppy, the
floppy just writes magic data patterns to the partition, afaik]

You can get the floppy image from ibm [as a dos executable only,
unfortunately, but if you have w2k you should be able to run it there] -
nose around in the downloads area for thinkpads.

However, even after running this, I still get a system invalid message when
I try to hibernate. Not sure why. 'swsusp' may be worth checking out.
[ haven't tried it myself - look for it on sourceforge. ]
