No problems, well for interest's sake, this is the `lspci -vnn` output
for the relevant device:

Ahh okay, so an update to the kernel will be worthwhile... I'll have a
look for the wireless-testing tree.  I was preferring to stick with
open-source drivers as I personally hate proprietary blobs in kernel
space.  Hence my focus would be to fix the open-source driver. :-)

I shall do a pull of the relevant git tree and see how it goes.

Thanks in advance.
