It's not a big deal if something is not supported by default. You compile the driver then "insmod" it in later. Or just rebuild the kernel. If it was once supported hardware you can keep it working.
Many times you need to use ISA cards because it is come custom hardware or one off interface. I've got a few of those that fortunately I don't need to use. But it taught me to NEVER build only thing on a card that goes inside a PC. Build instead using a standard interface to a PC, like USB even better a network connection.
