Alright I made some progress tonight and was able to boot my laptop with NuttX and have the PCI enumerate to the screen. The enumeration matched what I see when I am booted into Linux. This is not a real console as I have not implemented the full serial driver interface for it, but it can be used to debug early boot. Also if you want to hook your application without nsh you can just configure "CONFIG_USER_ENTRYPOINT". The demo example configuration on my branch is "qemu-intel64:earlyfb". --Brennan
