As far as I know this is not possible today with either Solr's 4.0 grouping impl or the new grouping module (soon to be grouping in Solr 3.x).
I'm not sure about the patch on SOLR-236 though. But it's an interesting use case; it's a compound group key, right? You want to group by a tuple (X, Y). Can you open a Lucene issue for this? I'm not sure we can fix it today but I think the use case is reasonable so we can at least discuss it on an issue...
