I'm running with a very minimalized dts (attached) to try to get to the point where a device gets matched correctly and disabled. I think devices that should be disabled are causing me grief in SimNOW.
This is a snippet of the log file that has me wondering what I'm doing wrong:

Skip to next device.
Even though there's a match, a new device got created (dynamic PCI: 01:01.0)
Because of that, the enabled flag gets lost.
You can't fix that in the dts. It's a code bug. I had a fix for the old device tree code, but forward porting will takes some time. I hope to create a working version over the weekend.
