# dmesg -a | egrep 'uart|puc'
puc0: <Dolphin Peripherals 4036> port 0x2000-0x201f irq 10 at device 14.0 on pci0
uart0: <16550 or compatible> on puc0
uart1: <16550 or compatible> on puc0
uart2: <16550 or compatible> port 0x3f8-0x3ff irq 4 on acpi0
uart3: <16550 or compatible> port 0x2f8-0x2ff irq 3 on acpi0

I have "nodevice sio" in my kernel config and kldloaded puc.ko and uart.ko.
