US electronic diversity visa (Green Card Lottery) question.?

You won't get the bum's rush because you are not ethnic Chinese. It has nothing to do with your ethnicity. If you pull up the application this is what it says:

"Your country of eligibility will normally be the same as your country of birth. Your country of eligibility is not related to where you live. If you were born in a country that is not eligible for the DV program, please go to Explanation of Country of Eligibility {this link will open in a new window} to see if there is another option available in your case."

Native: A person born in a particular country is a native of that country.

The instruction sheet contains the following information:

"Native of a country whose natives qualify: In most cases, this means the country in which you were born. However, there are two other ways you may be able to qualify. First, if you were born in a country whose natives are ineligible but your spouse was born in a country whose natives are eligible, you can claim your spouse’s country of birth—provided that both you and your spouse are on the selected entry, are issued visas, and enter the United States simultaneously. Second, if you were born in a country whose natives are ineligible, but neither of your parents was born there or resided there at the time of your birth, you may claim nativity in one of your parents’ countries of birth if it is a country whose natives qualify for the DV-2011 program. "

You are a native of HK. You were born in HK. You are not claiming eligibility based on where you live now, but based on where you were born. I doubt that the political ramifications of colony vs not will make the difference, although the application does include the word "normally," which must be in there for a reason. Possibly you can claim Ireland based on your father's country of birth since your parents were not living in England at the time of your birth, however, that argument fails if the HK SAR birth place fails so it doesn't really help your situation. There is no place on the form to explain your circumstance. It appears that the most straightforward way to fill out the application would be based on where were you born and see what happens.

You have nothing to lose. It is free to enter. You need to get your entry in by November 30th. Don't wait. The system is slow during the last days of the lottery. Better to submit your application early.

Your place of birth determines your eligibility and provided you can prove that you were born in Hong Kong, you won't have a problem. Hong Kong SAR natives are eligible so you are eligible. Your passport country means nothing.
