Yes, although lsmod just tells me that "b43" is loaded.  And
"dmesg | grep b43" shows this:

,----
| [    0.628622] b43-pci-bridge 0000:06:02.0: enabling device (0000 -> 0002)

The kernel configuration has these b43 related parameters:

CONFIG_B43=m
CONFIG_B43_SSB=y
CONFIG_B43_PCI_AUTOSELECT=y
CONFIG_B43_PCICORE_AUTOSELECT=y
# CONFIG_B43_PCMCIA is not set
# CONFIG_B43_SDIO is not set
CONFIG_B43_PIO=y
# CONFIG_B43_PHY_N is not set
CONFIG_B43_PHY_LP=y
# CONFIG_B43_PHY_HT is not set
CONFIG_B43_HWRNG=y
# CONFIG_B43_DEBUG is not set
# CONFIG_B43LEGACY is not set
CONFIG_SSB_B43_PCI_BRIDGE=y
