Yep, tried that.  No luck.
I think the clue is that it's trying to change root device to wd1a
when my FreeBSD (ie. second) drive is wd2 !  
My CD-ROM is wcd0c (and I assume therefore wd1).
I have consequently tried "hd(2,a)/kernel" and variations without
success.  "hd(1,a)/kernel" starts the device probe sequence OK and
seems to work best.  It just can't mount root.  :-(
