No.  The main purpose of hw_pci is as a container to support multiple
different platform specific PCI implementations in one kernel.  It's
exactly what you need for single zImage.

FTTC broadband for 0.8mile line: 5.8Mbps down 500kbps up.  Estimation
in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad.
Estimate before purchase was "up to 13.2Mbit".
