Subject: CPUFREQ: Mark e_powersaver driver as EXPERIMENTAL and DANGEROUS

Hello!

Sorry for late reply. I've been aware problem with "e_powersaver". 
Nobody ever e-mailed me :-)
So far I'm aware "e_powersaver" fully respects values given it by CPU. 
Only code added by VIA
seems to be faulty for me. As I understand ACPI P-States provide 
unstable 400MHz for system in question too.
If "e_powersaver" was based on outdated documentation I'm sorry. This 
driver was neccessary for systems with
C7 CPU's which didn't provide BIOS P-states. But it was in early and 
dark ages of first C7 CPU's.

Bye
