I'm guessing I shouldn't be unloading lirc_zilog. Have tried using 
/etc/init.d/lirc restart instead.

I tried replacing /etc/lirc/lircd.conf with 
/usr/share/lirc/remotes/hauppauge/lircd.conf.hauppauge. For the first 
time since I started working on this two weeks ago, irsend LIST "" "" 
shows something!

$ sudo irsend LIST "" ""
irsend: Hauppauge
irsend: hauppauge_pvr
irsend: Hauppauge_350
irsend: Hauppauge_WinTV_Nexus-S
irsend: Hauppauge

Unfortunately all of these give the "irsend: hardware does not support 
sending" message. Does that mean my issue is down to the driver?

On that last point, I feel rather foolish, having discovered
