I have a system with a Duo+ (and two external serial modems and two 
internal ISA modems) running kernel 2.6.7.  I have the serial driver 
compiled as a module.  During init (in /etc/rc.serial) I have:

 modprobe 8250
 setserial /dev/ttyS4 port 0xec00 irq 12 autoconfig ^fourport
 setserial /dev/ttyS5 port 0xec08 irq 12 autoconfig ^fourport

When I do 'dmesg | grep tty' I get:

 ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
 ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
 ttyS2 at I/O 0x3e8 (irq = 4) is a 16550A
 ttyS3 at I/O 0x2e8 (irq = 3) is a 16550A

These are not the ports from the Duo+.  However setserial on each device 
reports:

 /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
 /dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
 /dev/ttyS2, UART: 16550A, Port: 0x03e8, IRQ: 4
 /dev/ttyS3, UART: 16550A, Port: 0x02e8, IRQ: 3
 /dev/ttyS4, UART: 16550A, Port: 0xec00, IRQ: 12
 /dev/ttyS5, UART: 16550A, Port: 0xec08, IRQ: 12

And all of the modems run just fine.

I was seeing dmesg output like you are seeing and things didn't work 
right.  I don't know what the problem was, but in order to get rid of 
that messy (using "high" tty numbers) dmesg output I decided to not 
compile-in the serial driver into the kernel, but to use it as a module 
instead.  And after doing that I didn't see the problems any more.
