There may be some differences brought from the version difference. Ubuntu Natty is still at isc-dhcp 4.1.1-P1-15ubuntu9; which is only slightly below the version from Debian: 4.1.1-P1-16.1. The latest upstream release appears to be DHCP 4.2.1-P1.
We can update the packaging in Oneiric (or wait/ask for the Debian maintainers to update it), which will likely get the same behavior as 4.2.0 in Fedora. I haven't seen any of these details in release notes, but it's likely just been omitted.
For now I'll reassign this to the 'isc-dhcp' package since there doesn't appear to be any issue with NetworkManager, just unexpected defaults for the DHCP client and server.
