File xmit.h gives some hint. Following firmwares use new RX/TX headers: /* Tested with 598.314, 644.1001 and 666.2 */ Two drivers I've found [0] contain firmware for HT-PHY cards: broadcom-wl-5.100.104.2.tar.bz2 (FW: 644.1001) broadcom-wl-5.100.138.tar.bz2 (FW: 666.2) (I don't host any driver containing firmware 598.314) > As I am in the process of updating the install_bcm43xx_firmware script for > openSUSE, we need to decide how to handle the situation.

For distribution I propose something easier. If distro is using 3.1 kernel - provide script using older firmware. If distro is using 3.2 or newer - extract firmware from newer driver.
