Alternative to using swap for hibernating

[Sam Varshavchik <mrsam@xxxxxxxxxxxxxxx>]

I've been trying to figure out why one of my laptops just damn refuses to 
hibernate.  It starts the hibernation process, turns off X, begins shrinking 
memory, turning things off -- then boom!  it drops back into X, reconnects 
to wireless, and just keeps on chugging.  Without really showing any 
informative error message.

I finally found the clue in /var/log/messages:

Apr 11 23:57:55 lc2440 kernel: swsusp: Not enough free swap
Apr 11 23:57:55 lc2440 kernel: Restarting tasks … done.
Apr 11 23:57:55 lc2440 kernel: Enabling non-boot CPUs …

So, it can't fit the contents of RAM into swap.

This laptop has 2GB of ram.  I've partitioned the drive with a 512MB swap.

Now, I don't really feel like blowing 2GB of my laptop's hard drive on an 
essentially useless swap partition.  Besides, it's a bit too late for me to 
repartition.

Do I have any other ways to get hibernation working?
