I thought about it but I have to find the original writer and get 
clearance.  BTW, the source is not so clean and it needs some cleanup 
to be committable.  When I find some copious free time, I'll do

Awesome.

BTW, OpenBSD has bioctl(8) to manage RAID controllers:

http://www.openbsd.org/cgi-bin/man.cgi?query=bioctl&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html

It would be nice to have such an API for us too. :-)
