I know how you can move it back to ttyS4, anyway.  Look for your modem
in

$ cat /proc/pci

output.  Note the I/O at 0xNNNN and IRQ MM values.  Then do

# setserial /dev/ttyS4 port 0xNNNN irq MM uart 16550a

Your PCI modem should then be available at /dev/ttyS4.

There's no reason I can think of to do this if you intend to stay with
kernel 2.6, though (just symlink /dev/modem to /dev/ttyS14 and use the
modem as /dev/modem).
