I believe most of anaconda's "magic" comes from probing the PCI and USB 
bus for vendor and device IDs.  If you dig into a driver (for example, 
e1000e), you will find a pcitable listing all of the IDs the driver 
supports.  If you look in /lib/modules/<kernel>/ you will find a 
modules.pcimap and modules.usbmap among other bus types.

Hope that helps.

Cheers,
Mark
