>Description:
	Yesterday, I tried to install FreeBSD on an HP dc7600, the onboard
	NIC was not found during installation. After some investigations on 
	the web, I found this onboard NIC should be a Broadcom BCM5752, which
	is not supported by the current bge driver. Hence I wrote a simple patch	for this NIC.
