I recently bought a 2011 MBP 13" and did this. SSD with Win7 in the cd bay, 7200rpm drive with OSX in main bay. Boy is the 'no boot from USB' thing on the new Macbooks a giant pain in the ass! Installing it is one thing, but last night for some reason Windows wouldn't boot so I needed to to startup repair, had to unscrew the whole thing and put the superdrive back in to do it. Should have been a 5 min operation, wasted a days work (superdrive was at home). I wonder if I can make a 5gb partition on my main drive to be a windows install disk in case it happens again?
