Yes, of course. Some time ago I have completely rewritten an AVR910 compatible 
programmer on an AT90S2313, so I'm quite familiar with the protocol. i have 
obtained all information by studying the atmel source code of avr910 version 
2.2.

The avr910 will not perform a page write, unless it is told to by means of the 
"issue page write" command (that is 'm').

BTW: Before this command the address has to be the beginning of the page. The 
address is not changed by the "issue page write"-command.

I didn't find any 'm' in the avrdude-output. And there doesn't seem to be any 
related code in "avr910.c".

ATmega161, but the device type shouldn't make a difference ;-(
