This news came as a big surprise to me. Folks at Maemo Arena installed Google Chrome on a Nokia N900. They even have download link and a tutorials as well !
Nokia N900 can run firefox, but that’s a customized mobile version, but the Chrome deal is different. They have installed the full desktop version of Chrome on Nokia N900. It’s been ported from the 32-bit Debian package.
Instructions and Download link available here.
If you have a Nokia N900, it’s time for some experiments ! let me know if this works  for you.
