I agree, the interleaved protocol support is awfully high-impact for
-stable.  However as you've observed, the affected machines are really
unusable without some fix.

Personally I'm fine maintaining the backport locally, but it'd be nice
to fix this for Karmic as well.

I'll do some testing on non-Dell hardware tomorrow.
