Comment 102 for bug 952080

Alan, I think I can get my hands on an Asus motherboard for a couple of hours. I'd like to take a couple of snapshots (one with 5V and one with 5VSB) of the output from different tools and diff between them. So far I'm planning to do dmidecode, lspci -vvvv, dmesg, lsusb, hwinfo, acpi -V, cat /proc/acpi/wakeup, the whole /sys directory with debugfs mounted... Any ideas on what else could I run on it?

I'll try taking four snapshots: +5V before S2R, +5V after wakeup, (reboot), +5VSB before S2R, +5VSB after wakeup.

I'd also like to try putting the OHCI controller or a device under it (or the whole PC) on suspend mode and waking it back (either with code or by button) or otherwise poking it to force it to change some value in a register. If +5V and +5VSB behave differently, there could be a way to detect the setting on startup, but I have absolutely no idea on how to do that. Any clues? Any tools or code?
