PUC rewrite

I have been starting to take a look at moving some of our embedded 
platforms to RELENG_7 and noticed that support for the 3Com PCI cards 
are broken.  Previously, in pucdata.c, they were defined as

        /* US Robotics (3Com) PCI Modems */
         {   "US Robotics (3Com) 3CP5609 PCI 16550 Modem",
             {   0x12b9, 0x1008, 0,      0       },
             {   0xffff, 0xffff, 0,      0       },
             {
                 { PUC_PORT_TYPE_COM, 0x10, 0x00, COM_FREQ },
             },
         },


However, in the newer version they are not there, and uart is not 
picking up the device.

In the new re-write, what is the proper way to add support for 
devices no longer recognized ?

On RELENG_6, its seen as
puc0_at_pci0:14:0: class=0x070002 card=0x00d312b9 chip=0x100812b9 
rev=0x01 hdr=0x00
     vendor     = '3COM Corp, Modem Division (Formerly US Robotics)'
     device     = 'USR5610B USR5610B (0005610-02) 56K Performance Pro 
Modem (PCI Internal)'
     class      = simple comms
     subclass   = UART
