It will, but just letting the OP about PAE incase they didn't know. Many
people assume you need 64bit if you want to go voer the 4GB mark and not
know about PAE
Axel has a great email explaining PAE and 32 - 64 bit, for those who
need any clarification

Yes, you're right: 64bit gives you all you want;-)
However, 32bit together with PAE gives you a part of it:
- the 32-Bit PAE-Kernels can use > 4GB and distribute it to different
processes
- However, a single running process on the 32bit PAE-Kernel is limited
to 4GB of Ram.
So, when you have MANY processes running at the same time, each of which
uses less then 4GB, a 32bit PAE-Kernel might be sufficient.
On the other hand, if you have ONE process which will need more than 4
GB, you NEED 64bit-Kernel -- 32bit and PAE-Kernel won't be a solution
for you.
However, 64bit operating system is more efficient and flexible than
32bit + PAE-Kernel, as soon as you have 64bit hardware (That's my
personal opinion:-))
The main reason why people continue using 32bit + PAE is, that there are
some programs which do not exist for 64bit (like the new flash plugin
from Adobe, so no Google Maps street view on 64-Bit Firefox;-)). Then
you can either install a 64bit Kernel & 64bit Debian, and some 32bit
programs on top of it, or stay completely on 32bit...
However, on a server this shouldn't be a problem for you.
