I just wonder howPAGE_SIZEin determined in each architecture? Is it possible to use 8k or bigger page size in a i386 PC?Thanks,

You may run into trouble with something that calls mmap with a fixed address, with executables which have text sizes of odd number of small pages. I was told that these problems are fairly rare.
Running a bigger page size does nothing to help your TLB coverage, but it might improve paging performance (or it might not).

Only 50% of all binaries are affected... that's fairly rare :)
