rk,
I can't verify that they don't have to go back to 1997 for the quarterlies (10Q's), but I'm quite sure that's the case. They just need a year or maybe two worth of 10Q's so they have comparison numbers for the current 2011 periods, should they ever get filed.
But the SEC is requiring that they go back to 1997 for the annual reports (10K's), so the problem that you are concerned with still applies.
Here's what the SEC wants:
"In order to bring your filings current, please file your Form 10-Ks for the years 1997 through 2009, including audited financial statements as soon as possible."
I can link it if you need me to.
"I've been through it before, but don't remember where I ended up regarding the quarterlies. They absolutely AREN'T required for every year since 1997."
