Didn't know about register 70 until now, but I don't seem to need it...
I've been enabling this in a boot script (setpci -d 1106:3099 92=f9 95=1a)
ever since I bought the Board (Asus A7V266E with Athlon XP1700+).
Both the Enermax 300W powersupply and the power regulators on the Asus
board seem to take the extra stress well enough.
Temperature drops from ~70 degree to ~50 degree (which the board
measures using an external sensors, not the cpu diode), however
I'm shutting down the system every so often and because of that
my uptime is seldom more than 7 days and I can't say much about long
time stability. (Well, at the moment at least)
The TV Card does not like this at all, both the extra noise on the power
lines and the increased latency the PCI bus seems to have when this is
enabled. When I'm using the pci soundcard at the same time, whole
scanlines get missed. If I do a hdparm -tT /dev/hda in addition to that
I can reliably crash the system as long as this is enabled.
I also see a visible performance drop for the network card. (But not too
much, maybe 10%)
