That makes me think you're using AVRDUDE to program the device(s).
What's your exact commandline then? I have successfully programmed
boards with two chained AVRs in the past. Remember that each AVR
shifts by four bits, so you need
on one device, and
on the other one.
I didn't observe any specific clock issues, as when programming
through JTAG, everything inside the AVR is clocked by the JTAG clock
so it's independent of the main clock frequency.
