Both of those options have problems. PCI cards aren't built-in, so sometimes it MIGHT have problems auto-detecting and what-not. However, with PCI cards you can also add firewire ports (or get a USB 2.0 PCI card). The hubs sometimes have problems if one device needs a lot of bandwidth, or if the device needs to be powered through the bus. Regarding deep-sleep, I'm not sure. You're best bet would be to talk to the manufacturer you are considering buying from because they probably wouldn't advertise a compatability issue like that.
