Thanks, this sounds very encouraging and I will try it.

Another question is: are there any parts that won't work in amd64,
besides file format issue that you just mentioned.
Like NVidia driver? MPlayer plugins (taken from Windows binaries)?
Linux flush in browsers, it's originally only 32-bit in Linux and works
through the series of hacks in nspluginwrapper?
