I'm trying to use the latest amd64 kernel (2.6.17-rc3 compiled last week) with Debian Sarge 32-bit userland (is it reasonable to expect it to work?).

There's a problem with exportfs. I can export to IP ranges OK but I can not export to single hosts - nfsservctl() returns EFAULT.

Documentation/Changes tells I need at least nfs-utils 1.0.5, sarge has 1.0.6-3.1 so this should be OK.
