Hello, up to Fedora 15 including, there was ipv6 as loadable kernel module and was not problem disable/not load it. But recent F15 and F16 kernels have IPV6 support compiled in kernel, know anyone for which reason? For IPv4-only sites (which is absolute majority) this is unneeded...
The only reason I can see is to allow the ip6tables firewall stuff to work rather than take unknown protocol processing paths. Download the kernel source and rebuild if it really bugs you on memory.
