No.  It's a relic of a simpler time.

I only kept it because I didn't want to break any existing installs, but
updating the kernel's name is going to do that anyway.  Unfortunately
the current libxc code is broken in the worst possible way - it will
unlink an existing correct device and then fail to replace it - so even
if the system has set it up correctly it will still screw things up.

I think we're just going to have to have a flag day and fix kernel,
libxc and udev (assuming it needs it) all at once...
