Ugh.  I'm an idiot, that will teach me for having two sessions to boxes 
running at once.

Wrong info above, but the trace is still valid.

Correct info follows:

ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS14 at I/O 0xb400 (irq = 217) is a 16550A
ttyS15 at I/O 0xb000 (irq = 217) is a 16550A

06:02.0 Serial controller: NetMos Technology PCI 9835 Multi-I/O 
Controller (rev
01) (prog-if 02 [16550])
         Subsystem: LSI Logic / Symbios Logic 2S (16C550 UART)
         Flags: medium devsel, IRQ 217
         I/O ports at b400 [size=8]
         I/O ports at b000 [size=8]
         I/O ports at ac00 [size=8]
         I/O ports at a800 [size=8]
         I/O ports at a400 [size=8]
         I/O ports at a000 [size=16]
