For the recored here is the "crap" that's in FC1 and not in the stock 
kernel:

 From Trond's Tree:
    linux-2.4.x-rdplus.dif
    linux-2.4.x-cto.dif
    linux-2.4.x-pathconf.dif

 From -ac1 tree:
    kmap() calls changed to kmap_atomic() calls
   
Patches posted to this list:
    linux-2.4.21-nfs-accesscache.patch - reduces the number of otw 
ACCESS calls
    linux-2.4.20-nfs-ia64-EIO.patch    - increase RPC_RTO_MIN to HZ/30

And here are the patches that are in the stock kernel
and not in FC1 (yet)...

# 03/10/11  trond.myklebust@fys.uio.no  1.1148.17.6
# Make the client act correctly if the RPC server's asserts
# that it does not support a given program, version or
# procedure call.

# 03/10/11  trond.myklebust@fys.uio.no  1.1148.17.1
# Fix a deadlock in the NFS asynchronous write code.
