yes, it is a crosscompiling toolchain.

but there are no patches to add, you 
just have to add "--target=avr" to the binutils and the gcc. avr-libc is a 
dedicated libc especialy for AVRs.

there aren't anywhere conflicts!

on my pc, these modules run good and they have, like other crosscompiling 
toolchains also, a prefix ("avr-"). they are, suggested by Dennis, located 
at /opt/lunar/avr with a avr.rc script in /etc/profile.d to 
add "/opt/lunar/avr/bin" to the path.

uclibc, uboot or a kernel are not needed, because this microcontrollers have 
between 1kB to 256kB flash :)

about the intermingling: i think you mean the renaming from binutils-* to 
avr-binutils-* (equal to gcc-* to avr-gcc-*). it's just eyecandy to keep 
track of your sources in /usr/src.
sorry, i don't know another way...
