It can't, you have to use libata in order to get proper hotswap support. 
  For you this probably involves some kernel boot parameters to force 
the system to use libata pata, and rewriting /etc/fstab (unless you want 
to recompile the kernel and remove the old pata drivers altogether). If 
you can get that to work, your internal HDD will show up as /dev/sda and 
whatever is in ultrabay will be /dev/sdb when present.
