Primary homes ineligible for bankruptcy protection?

The kid has been transferred to his father who will hopefully be able to get him to sleep because I can't. <sigh> On the upside, this gives me a minute to read the NY Times. I came across the following snippet in an editorial (click here to read the whole piece) that discusses the current housing market and one bill that is being introduced that has the potential to help hundreds of thousands of people keep their homes.

"The bill also undoes a longstanding injustice. Under current law, mortgages on primary homes are the only type of secured debt that is ineligible for bankruptcy protection. Owners of vacation homes, farms and commercial property can modify those debts in bankruptcy court. But not your everyday homeowner."

What I want to know but am too tired right now to research for myself is if anyone knows this to be true. Are regular homeowners of primary residences not afforded the same rights as those who own vacation homes, farms, and commercial properties? If so, then I must once again yell about how the regular schmoe gets screwed and those with money build a system that benefits themselves to the exclusion of everyone else. In other words, if this is true, it sucks butt and we need to fix it.
