Thanks for your pointer.  Actually, I had undertaken the exact steps as
you mentioned, but I ended up with a lot of errors from the kernel.  Why,
I have no idea.  I have sent a mail to the list (nebsd-users), and so I
suppose you could help me with whatever doubts I have.

A doubt I have (I has asked this in my other mail also): you say you used
wd0f and wd1f for your raid.  Is it possible that after you make you make
a RAID 1 device (for mirroring), you can mount wd0f separately ?  I ask
this because (I have a similar setup as yours) but also have Linux, and I
want to mount wd0f from Linux.  Ofcourse I realized mounting it from Linux
could put both partitions out of sync, but I still ask ... :)
