Scratch that then!

Ah - yeah as you found out if you have anything connected to the MOSI/MISO/SCK 
lines it will kill your AVRISP, and maybe screw up the connected processor.

Yup - it's "v2" protocol. avrdude supports this, with "stk500v2" or "avrispv2"

I would say that's quite possible. What build / version of avrdude do you 
have? I was going to try causing the same failure you saw....
