  Good news, Simon made a patch that will create a fake table with all valu=
es
  (not only highest and lowest) using an algorithm:

  http://www.xtrarom.org/~juan/juan-est-plus-fake-table.diff

  I tried it on my Pentium M 745 1800MHz and it did show 13 frequencies.
  The known table for this CPU only has 6 freqs, so I thought the algorithm
  wasn't working correctly, but I think it's working fine because openssl
  speed seems to ok.

I think we should be conservative about these things and only use
values in the datasheets, at least by default.

I didn't see a note here, but I noticed that you committed most of
this and I've built and booted it on a Thinkpad T60 with a Core Duo.
I have one processor turned off in the BIOS; I had some bluetooth
trouble and haven't tracked it down but was suspicious of MP issues.

At 2167 and then 1000:

94k

well, setting to 1000 didn't go so well... (new keyboard, later):
