Not that I'm aware of.  :-)

Phoenix's website (http://www.phoenix.com) turned out to be quite
helpful in figuring out what was going on.  I ran phdisk.exe and
discovered that it's storing the hibernation data in c:\save2dsk.bin.
Just to be sure I ran strings on it and it was chock-full of all kinds
of debian linuxy stuff.

The phoenix website was helpful in figuring this out as well.  I do,
in fact, have ACPI.  Don't know if I have APM but I'm going to assume

Unfortunately it looks like that would require upgrading to one of the
2.4pre kernels.  Don't know if I'm up to that quite yet.  Anyone know
how easy/hard that is to do with potato, or would I be better off
upgrading to woody?
