ztdummy does not use the USB uhci host controller for timing in kernel
2.6 .

It seems that there are some problems with ztdummy rtc and the CentOS
kernel (or 2.6.18 in general? Anything that uses RTC? I hear suprisingly 
few reports about it with the Etch kernel. I wonder if there is actually 
a difference or just a report bias).
