Thanks very much!

So the best solution is probably to clean the current existing swap-partitions with the following two commands:
> dd /dev/zero /dev/hda4
> mkswap /dev/hda4
("hda4" only as example, to be named according to the real used swap-partition)

And boot with the boot option "noswap", in case high sensitive data will be used in the session.

I suppose that works, but I seem to remember a program in windows that would clean files off a (standard) hard drive permanently - but it suggested that 7 overwrites should be safe enough.  Don't know how paranoid that really is, but that would be running the dd command 7 more times!

Linux based disk wiper: http://dban.sourceforge.net/
You can also use "badblocks -svw /dev/disktowipe" from DSL to overwrite the disk four times.
I would guess that overwriting once is good enough.
