Oh, excellent:

 The format of a file name for a regular file is:
 /vicepX/AFSIDat/V1/V2/AA/BB/<tag><uniq><vno>
 V1 - low 8 bits of RW volume id
 V2 - all bits of RW volume id
 AA - high 8 bits of vnode number.
 BB - next 9 bits of vnode number.
 <tag><uniq><vno> - file name
 
 Volume special files are stored in a separate directory:
 /vicepX/AFSIDat/V1/V2/special/<tag><uniq><vno>

Thanks!
