Not sure what's causing the discrepancy here. Something in my driver?
(Broadcom wl.) Have to look into this more ...

Yeah, that's definitely the issue. strace shows this as non-root user:
ioctl(3, SIOCGIWNAME, 0x7fff32cf97f0) = 0
ioctl(3, SIOCGIWNWID, 0x7fff32cf97f0) = -1 EOPNOTSUPP (Operation not
supported)

ioctl(3, SIOCGIWESSID, 0x7fff32cf97f0) = -1 EPERM (Operation not permitted)
ioctl(3, SIOCGIWMODE, 0x7fff32cf97f0) = -1 EPERM (Operation not permitted)

vs. this for root:

Not sure what's causing the permission errors, though. (Don't know
enough about linux wireless.) Off to do more digging ...
