Can you send the output that shows that?

>bsdlabel shows on /dev/ad0s1 the six partitions, a, b, c, d, e, f

/dev/ad0s1 is slice one. (partition 1 in the dos/windows world)

That is exactly as it should be.

disklabel output can't give you mount points.  Can you provide the 
output from disklabel?  That would help in figuring out what's going on.

Here's a sample output from one of my systems:

# /dev/ad0s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
   a:   524288        0    4.2BSD        0     0     0
   b:  2045600   524288      swap
   c: 20964762        0    unused        0     0         # "raw" 
part, don't edit
   d:   524288  2569888    4.2BSD        0     0     0
   e:   524288  3094176    4.2BSD        0     0     0
   f: 17346298  3618464    4.2BSD        0     0     0
