That is an easy port but I will have to do that blind. Would you
mind take this for a spin on 2.4 first?

The more interesting part is if one should use other sized(16K or 512K) large pages too?
Those should be useful for user space but it is a lot of work. I haven't checked
what large page support for user space is in 2.6 for ppc though.
