As for QE: Note there was a devaluation imposed by the exchange rate, and the peg evaporated. So you are correct that Riksbank did not print, but the QE was achieved by the currency markets.
Nope, NYT is wrong on that one. I suspect they are referring to the implosion of the real estate sector which brought down a number of companies, but none of them where banks.
QE is a word with a specific meaning, it's not just a synonym for "stimulus". It refers to the buying of financial assets by the central to increase their value, and/or to increase the money supply. Ending a currency peg has nothing to do with that.
Note that the bailout operations that did take place did so after the end of the peg.
See, eg. http://www.nytimes.com/2008/09/23/business/worldbusiness/23k... , note the term "series of bank failures."
