This is my style of contributing, too.

In file http://git.savannah.gnu.org/cgit/simulavr.git/tree/src/atmega16_32.cpp
find constructor AvrDevice_atmega16_32::AvrDevice_atmega16_32().
(Or atmega128.cpp, attiny2313.cpp ..., they are all basically the same.)
There you see how and when the MCU peripherals are instantiated and
wired to the microcontroller (aka "core") registers and interrupts.
Catching register writes and reads, scheduling an interrupt should be
similar to any other peripheral.
(I am not familiar on how are these things wired to the outside.)

Nobody, I believe.
