Depending on the software you run, programs can take more memory due to
larger integers and pointer sizes. If memory usage is a problem, go for
a 64bit kernel with 32bit userland. Memory allocation above 896MB is
much more efficient on 64bit kernels because you don't have to use the
"highmem" method to access that.
