Hello.
I've applied the following patches and it seems ok for atmega64. Now I
think that avrdude.conf.in should be also patched for all atmega
regarding the tokens "read" and "write" (they have to be "read_lo" and
"write_lo") or stk500v2.c should be patched to look for other parameters
than AVR_OP_WRITE_LO and AVR_OP_READ_LO, I dunno what's the better
solution, I leave that to the gurus!
