That's the issue, look in Documentation/Changes for the proper version
of udev for the past few kernel versions to handle this kind of issue
(again, it was a stupid libsysfs problem, which caused us to finally
drop that piece of crud from udev...)  This has been documented as such
since last October, see commit ad7e14a55ed7648d02a4df8e460e291d80a18c98.

It was necessary to do this for the input drivers to get them to all
work properly, please see the old archives for details as to the
necessity of it.

Also, that change caused the creation of Documentation/ABI/ which
describes the rules that programs that look at sysfs class stuff, must
be able to handle a symlink there.

That older version of udev in 10.0 can't handle the symlink, but I think
that Kay had a version somewhere that was patched to handle it.  I'd
just recommend upgrading to 10.1 :)
