If you boot your kernel with -v, you should get the WWNN/WWPN printed out.

It looks like there is an ioctl (ISP_FC_GETDINFO) that you can use to get
that information programatically, but I don't think we have any tools in
the tree that will dump it.  It looks like Matt has some source in the isp
driver distribution that will probably do the trick.  See:
