FreeBSD EG20T UART driver?

[Andrew-333]

Hello again,

I've successfully loaded and begun to tweak pfSense for my application.  
But I just noticed that the precompiled FBSD 8.1 kernel does not seem to
support the EG20T PCH uarts at all.  The console is through the legacy
ISA UART implemented on the LPC bus (though FreeBSD complains "
<Non-standard ns8250 class UART with FIFOs> at port 0x3f8-0x3ff irq 4
flags 0x10 on isa0".  However, none of the EG20T's ports are recognized:

pci2: <unknown> at device 10.0 (no driver attached)
pci2: <simple comms, UART> at device 10.1 (no driver attached)
pci2: <simple comms, UART> at device 10.2 (no driver attached)
pci2: <simple comms, UART> at device 10.3 (no driver attached)
pci2: <simple comms, UART> at device 10.4 (no driver attached)

Of course only the first one is supported by the net 6501 board
hardware.  Is there a loadable kernel module that I can add to my system
or will I need to recompile a new kernel configuration?

Thanks,

Andrew

I am running FreeBSD 9.0-STABLE (r232394) and I get:
