System: NetBSD 2.0.1 NetBSD 2.0.1 (DELTA-1.11-20050129) #1: Sat Jan 29 15:31:14 ICT 2005 i386
Architecture: i386
Machine: i386
	NetBSD has no support for the Broadcom BCM4401-B0 chip/card
	found in Compaq (HP) nx5000 laptops (maybe other places too).
	It seems to be functionally identical to the BCM4401 which is
	supported by the bce driver.
	Try booting NetBSD on a nx5000 (or simply trust me...)
	The patch below is all that is required to support this card/chip.
	Note: there are no functional code changes, all this does is to
	add the device ID to the pcidevs file, and knowledge of it to the
	bce driver table of supported devices.

	With this change, the chip was recognised, and worked fine
	(though with only limited testing so far).

	I haven't included patches for the generated files, pcidevs.h
	or pcidevs_data.h - those you'll need to update in the standard
	way after patching pcidevs.

	The name "BCM4401-B0" comes from the e-mail message mentioned
	below - I have no independent verification that it is correct.

	This looks to be the kind of patch that should be pulled up to
	the netbsd-2 branch, so it would be appreciated if whoever does
	the patch could send in a pullup request.

	The inspiration for this patch came from an e-mail message on
	a FreeBSD list/newsgroup from Yoshinobu Inoue (Fujitsu, Japan).
