So far as I know, Speakup still doesn't support serial ports that aren't built-in to the computer. Since computers generally don't come with serial ports anymore, that is a huge problem. Somehow, there needs to be a way to pass IRQ and port addresses to the module so that such PCI serial cards can work. I've never encountered a PCI express serial card, so don't know if any special support in the kernel is required, other than the obvious of having support for PCI express in the first place.
