That works fine. In fact, just "iwlist scan" returns the same result - only 
the info for my AP is returned. (There are at least 6 APs visible from an 
another laptop sitting nearby.)

No, it just continues with the stream of "frame lost" messages:

eth2: Information frame lost. (10 times, followed by 1
__ratelimit: 2 callbacks suppressed  (then 10 more frame lost messages, and so on)

The number in "callbacks suppressed" varies pretty widely, from 2 to 32.

Using 9.48, I so far haven't found 9.52 for download anywhere.
