I have an ASUS A7V motherboard, similar to your ASUS A7V133. I find that stock kernel (2.4.18-pre7) APM powers off the machine, but stock kernel ACPI does not. However, the Intel ACPI patch, available from http://developer.intel.com/technology/IAPC/acpi/downloads.htm against kernel 2.4.16, does power down my machine. I was able to forward port this to 2.4.18-pre7 without too much trouble by starting with 2.4.16, applying the Intel ACPI patch first, and then applying kernel patch-2.4.17 and kernel patch-2.4.18-pre7.
As to the merits of the amd_disconnect patch that started this thread, under 2.4.18-pre7-acpi, I get an idle CPU temperature of about 48 C. With the amd_disconnect patch, it drops to 32-35 C, wow! As previously discussed, APM + amd_disconnect on an Athlon does not provide any power savings, one needs ACPI + amd_disconnect.
Note that on this motherboard (and perhaps all ASUS Via chipset motherboards, including the A7V133), one needs the following line in /etc/sensors.conf to get reasonable lm_sensors CPU temperatures: compute temp2 @*2, @/2 This is as described at http://www2.lm-sensors.nu/~lm78/support.html in Ticket 775.
