  Hack in the code from FreeBSD-5 to set the timings for NVIDIA/AMD chipsets.
  This seems to greatly reduce READ_BIG: ILLEGAL REQUEST problems accessing
  a CD on my AMD64 box (NVidia3 chipset, secondary controller, master, PIO4).
  The problem occurs at a much lower frequency in overnight tests.  Further
  testing is ongoing.
