Matt's come up with a new FPGA bitstream file that looks like it fixes
the weirdness for decimation==10, and flattens out the decimation==8

You can find the new file at 

... or miracle of miracles, it will now be installed automatically if you
update and build usrp from CVS.

The md5sum is:

  $ md5sum usrp_fpga.rbf
  17e5b8720470a2b3e904a48bae471ed3  usrp_fpga.rbf

N.B., if you are using the Quartus tools and compiling the FPGA from
the verilog yourself, this new behavior will probably be a problem for
you.  Every time you "make install" in usrp, your custom bitstream will
be overwritten by whatever is stored in CVS.

To keep this from happening, create a file called DONT_INSTALL_RBF in
the installation directory.  E.g., 

  $ touch /usr/local/share/usrp/rev2/DONT_INSTALL_RBF

Have fun!
