Just curious, how big of a difference (indeed, what difference) does
64bit make?
It will make all the difference on a box with 16GB. On a 32bit machine, you can use a PAE enabled kernel to allow the operating system to address all the memory, but you're still stuck with a 4GB per-process limit, which means if this will be a dedicated MySQL server, you're wasting 12GB of memory.

Why wouldn't Linux use that 12GB for applications and (more importantly) as a really big read cache?
Hardware and Software limitation. MySQL 32bits version can't use more than 2 GB of memory. It can't use 4 GB even using PAE.
