Thats a very good question, unfortunately I really don't have an answer 
for you though.

What it ultimately boils down to is that I think the support in FreeBSD 
7 itself is lacking in this case, which in turn effects us on PC-BSD 7. 
However, they may simply not be aware of the issue. You'll probably be 
best off reporting this to them here:


If the can get it fixed in 7-Stable before PC-BSD 7 is released, then 
we'll have the support as well. You may want to report it soon though, 
hopefully its just a simple fix, and they can get it put into the system 
quickly. If the support is in OpenBSD already, I'm sure they can port it 
pretty fast.
