[Bug 73275] P-M high idle CPU usage, reported as fixed, persists in edgy

[hardyn]

Public bug reported:

exactly the same problem with high P-M cpu usage as reported in dapper
and marked as fixed in  bug #30557; seems persist in edgy with "generic"
kernel.

problem can be worked around in same manner as previous by adding
maxcstate comment in start up script.

surveying the ubuntuforums.org, the problem seems to most commonly
reported on Asus P-M and Vaio P-M based notebooks.

Most reports are for Asus M6a, or Z70 notebooks (same notebook) and Vaio
FS.

simptoms are same as before, high idle cpu usage, 20-30% with radical
fluctuations, adding maxcstate seems correct symptoms, at what
performance penalty?
