there is a flashplayer working for 2.1. However without jit enabled (2.2's huge boost in performance) performance on sub 1.2ghz devices is abysmal. On my droid when running cyanogenmod 5 with the 2.1 flashplayer, most videos are flat out unwatchable slideshows. With Jit enabled in 2.1, there is a substantial improvement if you negate the constant FCs.
