Precious Metals Ira

Anyone knows a website that gives the list of ETFs that should not be bought within an IRA Account?
For example, there used to be a law that ETFs based on Precious metals should not be bought in IRA Accounts.
Maybe I should not have called it a law, IRS used to treat ETFs such as GLD as owning Gold (collectible). Any investment made in it would amount to a distribution. IRS changed it sometime back and now is allowing purchase of ETFs like GLD in IRAs. check this link:

There are other ETFs which if purchased may force us to file taxes even if it is bought with in an IRA, check this link:

I was hoping that among all the ETF related websites someone would be maintaining a list ( of ETFs such as those based on futures, commodities, foreign real estate) not worthwhile to buy with an IRA.
Thanks for the quick responses.
Really? What law was that?
edit:
Precious metals should not be bought in IRA Accounts or at all if you look at the last 30 year trend of gold for example.
I would prob not use leveraged investments (FAS, FAZ, SDS, etc) in an IRA unless you can handle the risk and volatility.
Short of that, there is no law that I have ever heard that prevent the purchase of an exchange listed ETF in an IRA.
