It turns out that Panasas is using the Java bundle from LSI on FreeBSD 
for Santricity management. It opens /dev/sg**. There's a change 
somewhere else to manage some 64 and 32 bit compatibility issues I'm 
going to pull in.

No matter how bad Linux can be in many respects, it has market share, 
and it benefits freebsd to be able to support tools, no matter how 
broken, from that platform.

The reason I also hit this situation is my virtual fake HBA has one test 
mode where it creates 2000 da devices. That's why I found this funny one 
for sg.
And, it turns out, this is not just a cosmetic issue.
