Sure that this is actually communicated to userspace? It appears that the
module is still loaded, with no devices bound.

Can't test right now, but I re-ran update-initramfs after the installation,
so I guess broadcom-sta is included in the device ID list.
Anyway, I wonder if it makes sense to declare support for that PCI ID if it
isn't actually present -- the probe function will always fail until support
for LP-PHY is implemented.
