Ignore the previous 7/7 patch; this one has the documentation updated to match the 33/66 MHz target names.
applied, thanks (esp. for the generic pci).
For future ref., boards must be added in alphabetical order in the 83xx section of the Makefile, and have an entry in MAKEALL (I fixed it this time).
