prototyping shield and atmega16 or 32

hello...

just a simple question.

Tom igoe has designed a prototyping board for arduino.. if we're modifing the schematics for an atmega 16 or 32...
can we use the bootloader and arduino's IDE for programing and compiling for this custom Arduino ?

I'm always in the idea to use only an avr and a LCD display... no more things to plug but i really need more ram for vars and software ::slight_smile:

regards

eric

PS : i love arduino, i start learning electronic and C to play with. cool work and cool forum. thks for your great job.
and no, i'm not sucking for an answer :-X
