NetBSD 5.99.29 can't recognize my bcm4312

[Elric <elric%anche.no@localhost>]

I was told netbsd -current could recognize this kind of wireless card,
but once built a kernel with

bwi*    at pci? dev ? function ?        # Broadcom BCM 4312 Wireless

in the GENERIC configuration, and installed the new system, it didn't
boot anyway.

So, what to do?
