    Crude and simple way would be to add

    config JS_RTC
    tristate "JavaStation RTC"
    depends on SPARC32 && PCI
    <copy help from RTC with s/will be called rtc/will be called js-rtc>

    in drivers/char/Kconfig, slap plain and simple !SPARC in RTC dependencies
    and put
    js-rtc-y = rtc.o
    obj-$(JS_RTC) += js-rtc.o
    in drivers/char/Makefile

    Objections?
