That is the bootloader from the froyo leak so it seems that the update did not install. If I am right and the update didnt install the 2.1 sbf will work. If I am wrong then flashing the 2.1 sbf will brick your phone. Its up to you (I take no responsibility if your phone ends up bricked) but all signs point the update not having installed at all and the problems being from from moving the entire contents of /system/bin
I suppose you could also try flashing the 2.2 /system sbf but wont help unless the update worked. I dont know what would happen if you did this and the update didnt work. It may help it may make things worse or it may leave you in the same spot.
