Where oh where have my Longtails gone?

Messed up mod-rewrite and we're not ranking for internal pages...

One of my sites was ranked rather well in a tough SERP but got the vast majority of it's traffic from searches in the well-written, deep articles within the site.

Jagger hit, and we dropped overall, mainly it seems as our URL Rewrite program hit a glitch, and 3 to 5 versions of each page had been spewed out, and once noticed quickly cleaned up. But of course they had all been found/cached at the time.

Anyway, now 1st and 2nd level pages are back to where they were in SERPs (or better) but the internal ones have dropped to 30th or so for text strings they used to show up 1st for.

Other sites are doing fine with longtails, so assume it's a hangover of our mistake, and we've just assumed time will heal all wounds, but it's been a while now.

Anyone run into same issue with specific solutions?

I have, but that was because of a database downtime issue, and others. I am getting back into the serps, but only because of age.
