a small addition. it is also possible to suspend with a hibernation file
instead of a slice. this file has to reside on the first DOS slice and
usually is created with the same vendor-specific tool as the partition is.
since i need windows around for the occasional firmware upgrades of my
thinkpad, that's what works best for me. of course you need to convert
your windows NTFS slice to FAT32, but who cares...

note that the above is meant to work with bios hibernation. the OS
hibernation (eg what XP does) also works with a hibernation file but this
is not the same. also note that up to now i only tried this with APM.

cheers, t.
