Hopefully Lance's PERC 6/I SAS already has its battery installed.  The 6/I
with 256MB of cache is decent enough that I'm not sure getting a better
controller would be a better investment than, say, adding more disks and
splitting the database I/O usefully among them.

Upgrading to PG 8.3 comes to mind as another option I'd consider before
getting desparate enough to add/swap controller cards, which is always a
scary thing on production servers.
