3.3v bootloader on my Duemilanove

Hi guys i am stuck i bought a Duemilanove to play with a few months ago now but i want to convet it to run off 3.3v.

does any one have any experince with doing this.

I was wondering if i could use the bootloader from a pro and change the voltage regulator. I think i would either have to remove the 16mhz clock or replace it with an 8mhz one.

Help would be great


I think using simple DC-DC regulator is the easiest way
