Yes.

But we're talking about servers that can address more than 32-bits worth
of memory or at least the MMU can. Processes are still limited to a
32-bit address space (4GBytes - whatever the os reserves ... 1-2Gbytes)
unless they use paging hacks (PAE) to obtain access to additional
memory. Apparently in practice, PAE is limited to 16Gb.

Still kind of limiting for a server.
