One thing I'd be interested to see is performance regressions/improvements on various games. Games like Super Smash Bros. Melee and Wind Waker run much faster for me. But Spyro: A Hero's tail runs like crap even in the menus on this branch, when it runs mostly okay on master even in game.
Here are a list of games with (known) regressions
NBA Live 2006 - Court Graphics are a fail (I got the fifo log from 2005)
