Default Screwed up swap while trying to get hibernate working; help

Thanks, that worked. Having been bitten before by "doing the
obvious", I was wondering if something else was required.

Which begs the next question... howsabout if I turn swap off as part
of the hibernation process? I.e. in /etc/hibernate/hibernate.conf
include the lines...

OnSuspend 00 swapoff /dev/sda6
OnResume 00 swapon /dev/sda6

or for that matter, what's the worst that can happen if I turn off
swap alltogether, and run out of memory? Is it catastrophic, or merely
inconvenient (additional programs refuse to launch)?
