  * The situation with the tpudrv10 RF TPU driver is even worse than with
  * tpudrv12: not only are we missing the original tpudrv10.c source,
  * but we don't even have a tpudrv10.obj to reconstruct from.
+ * The present reconstruction has been made from the 20020917 fw
+ * image that came with our D-Sample board.
  *
- * We are going to try reconstructing the necessary tpudrv10 bits
- * from the 20020917 fw image sans symbols that came with our D-Sample
- * board, but for now this C file is mostly a placeholder for compilation.
+ * The deep sleep functions haven't been reconstructed yet,
+ * thus the firmware needs to be built with DISABLE_SLEEP=1.
