I will remove NetworkManager & gdm from the default runlevel and try
that, yes.

No. There's an initramfs, but it's only used to unlock the encrypted
root filesystem. The actual driver for sda (ata_piix) is in the kernel.

I have another user reporting it on PowerPC, without an encrypted root.

Eventually, yes. To see if that would clear things up, but it didn't.
Even if I just leave the AP 802.11d info to fill in the regulatory
information (which you can see higher up, as it has the information
slightly wrong and includes channel 14 together with very high radio
power) the 5GHz channels are not included.

As said, will do an iw list with no other software having fiddled with
anything yet. The Cisco APs are in the vicinity so I may not be able to
stop them picking up the 80211d info though.

Regards,
Tony V.
