You can use the MAKEDEV script in /dev to create the extra device files.
In this case:

  cd /dev && sh MAKEDEV sd5

will create the files for your 6th disk.  I'm not sure why it doesn't work
when you create ths files manually.  The i386 GENERIC kernel config (which
is included by GENERIC.MP) has:

  sd*     at scsibus? target ? lun ?      # SCSI disk drives 

so it should be able to handle this (I'm not sure what the limit is - I
have a sparc64 with 14 disks which worked perfectly once I ran MAKEDEV).
