Thanks very much for the pointer.

May I say first that I was actually asking a general question,
rather than one about my card, namely:
if iwlist shows that the card does not support scanning,
is it a waste of time to try NM with that card and driver?

However, I am very grateful for any advice about my card.
I am actually running orinoco-0.15rc1
[tim martha ~]$ dmesg | grep orinoco
orinoco 0.15rc1STA (David Gibson <hermes gibson dropbear id au>, Pavel Roskin 
<proski gnu org>, et al)
orinoco_cs 0.15rc1STA (David Gibson <hermes gibson dropbear id au>, Pavel 
Roskin <proski gnu org>, et al)
(This is more recent than the kernel version.)
so apparently I have the above patch in place.

Unfortunately, I do not seem able to turn on monitor mode
in the way specified:
[tim martha ~]$ sudo iwpriv eth0 monitor 1 10
Invalid command : monitor

According to "iwlist eth0 channel" I am currently on channel 10.
[tim martha ~]$ iwlist eth0 channel
eth0      14 channels in total; available frequencies :
          Channel 01 : 2.412 GHz
          Channel 13 : 2.472 GHz
          Current Frequency=2.457 GHz (Channel 10)

Probably a rather ignorant question,
but what is the relation between monitor mode and scanning?

These are the settings for my card.
[tim martha ~]$ iwconfig eth0
