@Amigo,
Amigo - sorry was away and am only here briefly but want to answer your questions.
Yes, the banks get $3 trillion (the $11 trillion is a theoretical maximum under applicable programs, and may theoretically even double, as per link I posted above) and your house too. The only way you get something back is if the house fetches at auction more than principal, accrued interest, and other expenses due to repay the bank, plus foreclosing agencies, legal fees, and taxes.
Have you no way to contact either the bank or a law firm or your local DA's office? If you really have 75% equity in your home there should be some way of keeping it. 2.7 million families are in some stage of foreclosure today - not that it makes things any easier for you, I know. Post here, I'll make sure to look in again soon, or send me IM which gets forwarded to my e-mail.
