proper enabling of AMD K7 power saving

[Malte Gell <malte.gell-Mmb7MZpHnFY@public.gmane.org>]

Hi,

i have an AMD Duron 750 desktop computer with Via KT133a chipset and to 
get some noticeable temperature decrease I need to invoke a command 
from the Athlon Powersaving Howto for this chipset
(http://www.tldp.org/HOWTO/Athlon-Powersaving-HOWTO/
approaches.html#commandline )

Is it right that it is the fault of the mainboard manufacturer if one 
has to invoke such a command to get C2-level for power saving?

Will Linux-ACPI one day address this problem so a user doesn't need to 
invoke something like "setpci -v -H1 -s 0:0.0 52=$(printf %x $((0x
$(setpci -H1 -s 0:0.0 52) | 0x80)))" to enable proper power saving?

My fear is just one day I buy a new mainboard and there's no appropriate 
setpci-command on the Powersaving Howto and Linux-ACPI doesn't enable 
C2-powersaving if the mainboard doesn't do it first... 

Why the f*** do mainboard makers not offer a BIOS switch to enable this? 
Besides the lack of out-of-the-box C2-level ACPI just runs fine. I 
guess if new generation mainboards (KT400 and up) would better handle 
K7 power saving we wouldn't need the Powersaving Howto, right?

regards
Malte
