Having delved a bit deeper into F10's "partitioning" scheme, actually,  
it's not as flexible as one might hope.
There are a very small number of relatively large pages and you have  
to partition on page boundaries
which leaves you with only limited flexibility when it comes to the  
CAM partitioning.

Bottom line, in a few years, everyone carrying full tables with F10  
gear will probably need to
upgrade all of their line cards to quad-cam.

Another thing to note (as near as I can tell, this applies to all  
vendors).  All line cards will function
only at the lowest common denominator line card CAM level.

IOW, if you have single, dual, and quad-cam cards in your F10 chassis,  
they'll all act like
single-CAM cards.
