The reason FC6 doesn't boot is there is a userspace tool
I believe in the initrd that cares about symlinks when it should

What is more interesting is that currently there is a bug in
2.6.35-rc5 where rmmod <netdriver> modprobe <netdriver> will in fact
fail.  There was an inadvertent regression and no one has noticed or
complained.  I spotted it by code review just a little bit ago and I
haven't had a chance to write and test the fix yet.

If the code is going to start bitrotting and no one is going to
notice or care simply removing the code instead of subjecting users
to weird unexpected breakage seems like a responsible thing to do.
