Take a look at the avr-libc FAQ. There an answer there that 
lists the "calling convention", which is how to right 
assembly routines that can be called from C routines. It 
tells you which registers get used for different things, 
i.e. which registers you can clobber, which have to be 
restored, etc. This should probably help.
