freebsd stable - Apr 2013 - fusefs-kmod does not work on 8-STABLE?

Hey all,

I've got puzzled with the fact that fusefs-kmod apparently does not on
recent 8-STABLE: it builds and loads, but I don't see normal "fuse4bsd:
version 0.3.9-pre1, FUSE ABI 7.19" like I do on 9-STABLE (installed on the
same laptop with almost identical kernel config).

The result is that /dev/fuse0 never gets created, and any fuse mount
attempt results in this message:

  fuse: failed to open fuse device: No such file or directory

Quick googling did not give me any good clues; perhaps someone here on the
list knows better how to remedy this problem?  Thanks,

FUSE is pretty bad outside of FreeBSD 10 where it's rewritten and part of  
the kernel. If your environment would be OK with making the leap to  
FreeBSD 10 I'd recommend it.

I've traced the problem down a bit, it seems to be due to some weird
brokenness of building modules outside the kernel: .ko file loads, but
modevent() functions apparently does not execute at all.

Also, nvidia.ko can reveal this (or related) bug by spitting messages
like this:

  link_elf: symbol linux_ioctl_unregister_handler undefined

This behavior was reported by arundel@ back in 2009 on -current@, but
the root cause was never found.
