most pcmcia cards are found on laptops, but desktops can use them as well (with extra hardware, obviously), so they aren't automatically ignored by desktop kernels. As for the acpi problem, it's related to power management, and as I don't use a 64bit system, it might be something related to that. most systems offer a boot option like "noacpi" or similar to disable this, you'll have to see if yours does, and make the necessary changes to your boot record (or the installation boot process, if you're doing a fresh install). Most of the time it's harmless, it's just telling you that it isn't available, but sometimes it can keep a system from starting up correctly.
Hope this helps.
