	IPv6 in Fedora Core 2&3 are enabled by accident and are not configured
properly and CAN interfere with DNS resolution due to timeouts
attempting IPv6 requests.  But that doesn't appear to be your problem
here at all.  IPv6 will not interfere with IPv4 in general and certainly
not interfere with DHCP.

	Looks like you're not getting any response to DHCP.  Could be the DHCP
server is not functioning or it could be something like a firewall in
interfering with it.

	Someone else already mentioned disabling it by aliasing protocol family
10 (net-pf-10) to off.  That prevents the kernel from automatically mod
loading it when one of the apps references PF_INET6, which is how it's
getting accidentally turned on.  Of course that doesn't prevent it from
being manually loaded.  :-)  The module is still there...  You also have
to reboot the system in order to remove IPv6 from the running kernel.
You can not simply rmmod it.  No workie...
