is there a time line on a 32 bit release for GNU/Linux?
Please see https://fold.it/portal/node/993282 for discussion on that.
From the FAQ:
"Q: How can I run Foldit on 32-bit Linux?
A: Unfortunately we do not support 32-bit Linux at this time. A workaround is to run the Windows version using WINE (http://en.wikipedia.org/wiki/Wine_%28software%29)."
