Extended Pagins on IA32

Hi,

I have a VM question again and would be grateful if you could give me a
quick answer:

Does Linux make use of 4M page sizes (or 2M if PAE is enabled)? If yes,
under which circumstances are large pages used?

I am posing the question because "Understanding the Linux kernel"
correctly mentions PSE as a CPU feature, but states in a sense that Linux
does not use a large page size.

But then again: if this is correct, what is the kernel option
"mem=nopentium" good for?

Many thanks and best regards

Oliver
