If the number of groups isn't too large, the hash aggregate system in 7.4
might speed up your query enough. By using hashes, the sort step is
avoided which will speed things up for large tables.
7.4 won't be out for a while, but the feature is already in CVS so you
can see if it will help with your problem now.
