Comment (by rock):

 I gave up, and booted to 32-bit Knoppix using the same Knoppix DVD and
 unpacked the 32-bit
 Tor Browser Bundle and it worked fine.

 So, the problem is that the 64-bit TBB doesn't work on 64-bit Knoppix.

 Googling, it seems I'm the only one reporting the problem on Knoppix, but
 tons of people have the same problem on Ubuntu, so, it's a 32-bit/64-mix
 mixup either on the Knoppix side or on the Tor side
 (I'm not sure which because I don't understand the problem).

 Nonetheless, the 32-bit TBB works just fine with the 32-bit Knoppix:

 So, in summary, here's how to reproduce the problem in five minutes:

 1. Obtain a Knoppix boot DVD (http://www.knopper.net/knoppix/index-
 en.html).
 2. Boot to 32-bit Knoppix (e.g., knoppix acpi=off xmodule=nv for the
 Lenovo W510)
 3. Download and unpack and run the latest 32-bit TBB (it will work).
 4. Now boot to 64-bit Knoppix (e.g., knoppix64 acpi=off xmodule=nv for the
 Lenovo W510)
 5. Download and unpack and run the latest 64-bit TBB (it will fail).
