Hmm, note that Linux on IP32 does:

static unsigned char ip32_rtc_read_data(unsigned long addr)
{
        return (unsigned char) mace_read_8 (MACEISA_RTC_BASE + (addr << 8));
}

static void ip32_rtc_write_data(unsigned char data, unsigned long addr)
{
        mace_write_8 (MACEISA_RTC_BASE + (addr << 8), data);
}

Where mace_read_8 and mace_write_8 access (MACE_BASE + __offset), __offset
being the first argument.  Our bus_space code for sgimips OTOH, attempts to
access (MACEISA_RTC_BASE + (__offset << 8) + 7) instead if I convert the
parameters to match the linux nomenclature here...

I'm not sure why com@mace works but the RTC doesn't and I can't find the
sparse bits of docs I have  ATM.
