   That did it. Thank you. After recompiling and rebooting the kernel, I
noticed via dmesg that when kldloading ssb the module complains with :

      ssb0: <Broadcom BCM4312 802.11a/b/g Wireless> mem
0xf9ffc000-0xf9ffffff irq 17 at device 0.0 on pci12
      ssb0: unsupportted coreid 0x817

   When kldloading if_bwn (after bwn_v4_ucode) the machine freezes. I
guess my hard isn't supported yet.
