Check if you can re-assign PCI IRQ's in the BIOS and have a look at `cat
/proc/interrupts` & compare with `lspci -v`, `lsusb` - you'll want to
have a dedicated IRQ for your external audio-device(s). ieee1394 is easy
enough, USB requires a bit more digging:
Some laptops have internal USB-hub(s) rather than multiple
controllers/busses. If you can boot the laptop in the store, also take
eg. a memory stick with you, plug it into all ports and check the
bus&device id with `lsusb`.

Wifi is sth. to test as well.. I'd not recommend nvidia but that's a
whole different story..
