I'll try here- I've not gotten it successfully installed here today- 
I'm working around the problem that I don't have a floppy drive on the 
machine, and the drivers are distributed as floppy images...  Taking 
forever to shuffle disks around here.

I'm not really familiar with the internals of the 3Ware drivers, but I 
*think* it's similar- the docs say it presents itself as  /dev/da0 to 
the filesystem.  Additionally, after install, the sysctl interface to 
the RAID is done like:
# sysctl hpt374.status
# sysctl ?w hpt374.status=?hpt rebuild a,b,0?

So I'm not sure if that answers your question or not here- but perhaps 
it provides some more clues?

Excellent- thank you!

Cool- much thanks Charles.
