Yep, that looks very much as a "side effect" of 4K stacks.

The next SL 4.X i686 kernel will have this option changed (it requires
disabling netdump patches).

I would suggest to use SL4 for x86_64 for your file servers (providing
you have hardware which can support it): 4K stacks are issue only on
32bit architecture.

Unless you have applications using DMAPI (Data Management API): no.
(AFAIK there are not many such apps available for now ..)

As far as I can tell 2.6.13-3.el.rf is just rebuilt of 2.6.13-3.rf
without changes (looking at spec file)

Yes it will work.
BTW: I looked little bit at CentOS XFS kernels hoping that they will
have a newer codebase of XFS there .. nope: it seems that they just do
the same as we (plus enabling 4K stacks) .. unless that changed recently ..
