I have tried this patch series. It allows the g3beige target to use the RTL8139 NIC, but the mac99 target still does not load the driver for this NIC. For some reason the IOKit is deciding that this device isn't going to have its driver loaded on the mac99 target. Hopefully the unknown requirement will be found.

Would you like a custom version of the RTL8139 driver for your Darwin installation? I can have it print  information that could help you know if it is working and give you the installation directions.
