Not sure what the significance of eeepc is in this case - mine being a standard Intel 5400 chipset I would have thought that's the last place to look for interesting things! > Which is not at all necessarily a given - I suspect it depends on just how > the power rails are set up on the motherboard.

Do we know this for sure that PCI-E bridges + Suspend have worked for others - In this thread at least I think people reported tg3 worked but not necessarily with a PCI-E bridge. Parag
