Can MySQL 5.4 beta be compiled for 32-bit processors under Linux?
According to this blog it's only available for 64-bit machines.

First, the preview release of MySQL 5.4 only includes the InnoDB scalability fixes (addressing more CPU's/cores). Second, it is limited to the Solaris and Linux 64-bit platforms at this time. The other features mentioned in this article and additional platform support will be appearing very shortly, so be looking for upcoming announcements soon. http://74.125.93.132/search?q=cache:iLgUTcXAmGUJ:mirror.facebook.com/mysql/tech-resources/articles/mysql-54.html+mysql+5.4+64bit+only&cd=9&hl=en&ct=clnk&gl=us&client=firefox-a

if you can run ./configure
and make
without any errors, it should work properly.
The current beta only has binaries for some 64-bit versions, but if you're keen on starting to beta test right now you should be able to compile from the sources on a 32-bit systems. (It IS a beta, of course, so unreliability IS to be expected -- don't run it in production, whether on 32-bit or 64-bit systems!)
