PS1, Line 77: 					subsystemid 0x1849 0x1e1a
> Note: The subsystemid is now applied to the NIC, but not the root port.

I copied this idea from mb/gigabyte/ga-g41m-es2l, and it seems to work.

If the id is not applied to the rootport, is there anything that we can do to change that to make this better/more correct?

Thanks!
