Jeremy,

I loaded smb.ko and it fixed the situation.  I had the line  
'ichsmb_load="YES"' in my loader.conf and it loaded smbus.ko but not  
smb.ko for me.  Seems like a module load dependency issue.

Here's my output:
attack:~ root# smbmsg -p
Probing for devices on /dev/smb0:
Device @0x44: rw
Device @0x50: rw
Device @0x52: rw
Device @0x64: w
Device @0x80: rw
Device @0x88: w
Device @0x8c: r
Device @0xc4: rw
Device @0xd0: rw
Device @0xd2: rw
Device @0xe4: w

Thanks,

Chris
