Intel box with > 4GB? It is possible with a patch like hugemem in Linux but
4GB should only be used 2^32 = 4GB. - The hugemem patch for instance allows
you to use all 16 GB but at a performance penalty.
I have 168 32-bit machines (IBM HS20 blades) which can take 8GB RAM each, although we don't have them configured with that much. So there are plenty of these machines available.
I tend to agree though, that for MySQL, if you want lots of memory its better to go for a 64-bit platform. We've been using Alphas and Tru64 for MySQL databases for years.
