Swap on raid1 IS possible with version 0.90. As has been suggested by
others I'd also recommend setting your partitions to type fd to allow
autodetection & automatic startup.
Just turn off your current swap, create a raid device from your swap
partitions, use mkswap on the raid device, change your swap entry in fstab
to use the raid device and turn swap back on agian.

That's why I'm using wap on raid in my production servers as well; with ide
disks failure of one of the disks is handled very well, on scsi raid
systems there have been numeous reports that the scsi layer or driver will
have problems after a disk failure and you may have to restart the system
after a disk failure.
