Good news, Simon made a patch that will create a fake table with all values
(not only highest and lowest) using an algorithm:
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.
dmesg with this patch: http://www.xtrarom.org/~juan/new_est-1.dmesg
And tests made with openssl speed:
Could you please test this patch on NetBSD if you have a SpeedStep
capable CPU and report results of all frequencies running openssl speed
(only first three values is enough).
