I guess I was unclear in my original post above: I only brought up the lspci issue because the card had to be re-initialized. If the card has to be reinitialized to show up on the bus, will we hit an issue where the windowing system says "I want to run something on the discrete card" and the kernel comes back with "What discrete card? There's nothing there." Just because the card was off and therefore not showing up as a PCI device, when inreality it IS there and is working perfectly fine, its just...off.
No announcement yet.
