That sounds more like something weird about the card itself than with the driver; “power saving feature” makes me think a faulty hardware ACPI implementation by the card vendor is to blame. I’ve had a similar thing happen with my Wi-Fi modem where it would completely crash and only a reboot would fix it; I too have to do special kernel options to get it working.
