A wild guess... (You gotta to provide more details rather than just PCI
IDs).
My guess is that it's using these chips:

http://www.winchiphead.com/product/ch353detail.htm
It didn't talked about possible cards' configuration so I used BAR0,
which could be 0x14, 0x18, etc.
Actually, the main chip there is CH352L. Plus there are two more chips
ST75185C, one per COM port.
Your patch made this pci device to connect to uart driver: uart2@pci0:8:1:0.
uart2: <16550 or compatible> port 0xe880-0xe887,0xe800-0xe807 irq 17 at
device 1.0 on pci8
uart2: [FILTER]
Also new devices showed up:
/dev/cuau2
/dev/cuau2.init
/dev/cuau2.lock
/dev/ttyu2
/dev/ttyu2.init
/dev/ttyu2.lock
cuau2 is probably the same as COM port. I don't have an easy way to
check now.
I believe adding another entry with 0x14 would add the second COM port.
Thank you!
Yuri
