I don't get it - with my present, still 9.99.47 setup, I am able to
load modules:
...
➜  xci modstat tun
NAME                       CLASS    SOURCE   FLAG  REFS    SIZE REQUIRES
➜  xci modload tun
➜  xci modstat tun

tun                        driver   filesys  -        0      11 if_tun

So is the option of loading them as per the above no longer available?
