You need to care about the _actual_ error, not the report there is an
error. The error is (usually) reported to the console.  Reboot the
computer and type this:

dmesg -c > /dev/null
modprobe ztdummy
dmesg

The output of the second dmesg will show you exactly what the error
message is.

Being that you have 'hpet' enabled, it's going to be 'Input/Output
error'. There's code in the kernel rtc driver that doesn't let you use
it if hpet is on:

--snippy--
int rtc_register(rtc_task_t *task)
{
#ifndef RTC_IRQ
        return -EIO;
#else
        if (task == NULL || task->func == NULL)
                return -EINVAL;
--snippy--

[From your kernel config]
> >>CONFIG_HPET_RTC_IRQ=y

So. Turn that off, and recompile the rtc module and it'll start working
