There is no "100 line rule" for -stable patches, if that is what you were referring to.
Please just send the patches to stable@kernel.org, along with a full description of why they are needed in 2.6.25.x. If those fine folk see a problem with merging the patches then they will explain that problem and discussion will ensue. It will not involve the term "100 line rule"!
