Can you not also use "swapoff=YES" in rc.conf? I have that in mine on my
Ultra1 and Alpha's, which if memory serves is for this very problem.

I haven't rebooted mine for ages so I can't remember if this does fix
it, besides, it crashes with this sleep forever lockup, so all the RAID
partitions are dirty on boot-up. :-)
