This would be my "personal" (in terms of keeping deltas in the
packaging) preference:
- make sure the patches get backported down to 6.12.y
- drop our local revert
- make uses affected made aware of the kernel parameter to use (maybe
  via a NEWS entry?)

I had a short discussion on IRC with Ben about that, and as the
upstream changes are not yet down to 6.12.y the situation is rather
clear that we have the revert. If the changes goes down to 6.12.y
though I would love to rediscuss if we could consider the above
instread.

I though realize it is too early to at all consider, given it's not
yet applied upsream.

Salvatore
