I'm seeing something similar too. NFSv3 export of an ext3 partition
to another machine in my lan fails (client gets permission denied)
when the server runs 2.6.24-rc4. It worked fine in 2.6.24-rc3.
There's no NFSv4 of any kind on either client or server.

And you're not varying the client at all, you're only changing the
kernel version on the server?
There are literally no commits between v2.6.24-rc3 and v2.6.24-rc4 which
touch fs/nfsd/. What filesystem are you exporting? Are the nfs-utils
versions the same in both cases?
Also, could you get a network trace showing the failure?

I get a "permission denied" when trying to mount a localhost nfsv2/3
exported volume, on v2.6.24-rc4-124-gf194d13. It works w/ nfsv4 mounting.
It worked fine in 2.6.24-rc3. Here's a sequence of ops I tried:
# mount -t ext2 /dev/hdb1 /n/lower/b0
# exportfs -o no_root_squash,rw localhost:/n/lower/b0
# mount -t nfs -o nfsvers=3 localhost:/n/lower/b0 /mnt
