Here are some outputs from gdb:

Tracking is implemented by the NITE binaries from PrimeSense. These make use of SSSE3 instructions, so unfortunately they just don't work on older computers.

The NITE source code is proprietary, so all I can recommend is requesting a less-optimized release of NITE on the OpenNI-dev mailing list.
