I have a new stk500 without a 45D021.(because atmel no longer makes 5V 45D021).
Are there an good way to soder in a 3.3V dataflash and still run the AVR at 5V (I need 16MHz on a mega16)?

Use 3 diode solution or check APP on Atmel Site how to interface DF with MCU (datalines can connect directly)...

Voltage divider 1,5k-3,3k->GND should be good. Worked for me for a 3V MMC.
