I fed it the stuff I downloaded today from this URL:

http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=2643&OSFullName=Linux*&lang=eng&strOSs=39&submit=Go!

which gets me a microcode-20080401.dat that does the same thing.  Is there
some *other* Intel-supplied microcode data I should be getting instead?

(If I should be looking elsewhere, can somebody fix http://www.urbanmyth.org/microcode/
to point somewhere other than http://downloadcenter.intel.com/default.aspx so
people go to the right place?)
