Is there a way currently to utilize 4M page size with FreeBSD for large
data set programs (to optimize TLB misses)?

FreeBSD/i386 uses 4MB pages to hold the kernel text and data, but there
is no way (to my knowledge) to ask the pmap layer for a 4MB page after
that either from the kernel or from userland. However, it's also my
understanding that most non-Xeon CPUs only have a 4kb TLB, and 4MB pages
are just broken down into 4kb chunks for it.
