yes i know ,it´s depend of hardware, but maybe we can do something as mmu with software or something like this , i don´t know.

No, the software cannot patch the hardware.
The MMU does address translations in 4 kB blocks and there's nothing you can do about that.

No, but you can fake it ;-)
I'm taking a wild guess here that you're interested in this subject because of distributed shared memory. That is, you're interested in smaller page sizes because you want to be aware of changes done to memory structures in sizes smaller then a page.
If so, you might want to check out how the Millipede system from the Technion works - it basically creates several "views" of a page using segmentation and other MMU features which creates artifical locality of memory structures on the same page in units smaller then a hardware page.
Hope this helps,
Gilad.

Bah... forgot the link:
http://www.cs.technion.ac.il/Labs/dsl/projects/millipede/default.htm
and you might have to dig through to find the actual place where they discuss this particular technique. AFAIK they've tried many different one and this ISN'T the one they're currently implementing...
