Did this fix your NFS problem? I'm working on discontiguous memory platforms as well.

It is intended to fix dcache flushing issues when using HIGHMEM support. We get much better results with this patch applied, but I would not characterize our 2.6.24 port as stable, yet, so there may be other HIGHMEM-related issues.
Yes, we are able to boot using NFS with this patch. There are some other minor changes that appear necessary for correct cache flushing but which don't seem to be causing any actual issues. (Cache stuff just works that way--you don't know you've got a problem until you get into some obscure corner case). I'll post these as soon as I can get to it.
I can't say whether these are all the changes required for high memory support, but we sure get a lot farther when we use them...
