That is most likely udev related, which doesn't really like module names
and default interface names changing for a known MAC address, depending on
your distribution (the following example assumes debian sid, udev 0.114-2)
you might have something like /etc/udev/rules.d/z25_persistent-net.rules
(which lists MAC addresses and the associated persistent interface name),
removing the corresponding stanza for your Broadcom wireless card (or
removing the whole file alltogether and letting udev (or rather
z45_persistent-net-generator.rules) recreate it during the next boot will
most likely fix it.

This issue is in no way b43 related, it happens with "every" networking
devices with changing module names (at least for every legacy wireless
module being replaced by a new mac80211 based driver).
