[ltp] Creating Hibernation file

I have a T23. I used to have a fat16 (or maybe fat32) dos partition 
(no windows installed) in which I created a hibernation file using 
the utility from the IBM website. This worked partially but there 
was always corruption of the screen in virtual terminals 
(Ctrl-Alt-Fn key) and it didn't work too well with KDE etc - e.g. 
always logged out automatically.

Recently I restored XP and lost the hibernation file. I then 
experimented a bit.

I reduced the size of the XP partition by half a gig (using the disk 
partitioning tool on a mandrake 9.1 install CD). I did not create a 
partition in the new space which was after the XP partition 
(/dev/hda1) and before the mandrake partitions (/dev/hda5, 6 and 

I then booted from the hibernation-creation floppy and tried the 
'create hibernation partition' option and off it went. There seemed 
to be no way to choose a partition to use and I was getting ready 
to see my XP and/or linux partitions disappear but in fact it had 
recognised the unused space in the middle of the drive>

Since then, both sleep and hibernation work much better with no 
screen corruption at all. Nor am I logged out of KDE. In fact it 
works just as I had always assumed it would - all open apps are 
restored to the state they were in before sleep/hibernation. 
Sometimes it is necessary to restart sound or the network but 
that's not a problem.

All usual disclaimers apply but it worked for me.

One question - sleep and hibernation only work if AC is 
disconnected. Is this usual? Obviously it can be argued that if the 
AC is connected then no form of suspend is necessary.
