Probably not. The new driver (bcm43xx) is not yet in a stable kernel (wait for the final release of 2.6.17, which should be just around the corner now). When it is, wait for your distro-o'-choice to use that kernel or newer and you'll have support (you will need to download/ extract the firmware separately though since the distros do not have permission to redistribute the firmware). (If you have a BCM4318 chip though, you'll probably have to wait until 2.6.18).
For Kismet, IIRC, you will need to run one of the development versions, rather than the latest stable, for bcm43xx support.
