Even with a lot of system RAM, this is kinda risky. I think a better approach would be to create a logical volume group--primary volume being the RAM drive, secondary an actual disk partition--and mount it as swap. That way you get the best of both worlds: ultra-fast swap space that spills over to disk if necessary.
