This rumor would usually strike me as slightly dubious, but it comes from the solid source Go Nintendo and is in some respects plausible. Basically, the word from particular anonymous GameStop insiders is that the store is going to be offering a special promotional DS Lite bundle this Mother's Day. Yeah, you read that right-- DS Lite, not DSi.
The exclusive bundle packages a copy of Nintendo's Personal Trainer: Cooking with a Nintendo DS Lite in the new, long-awaited Lime Green color. This is where the rumor really kind of falls apart for me-- why release a new DS Lite color after the DSi is on the market? Most of all, why tie the release of the Lime Green DS Lite to a Mother's Day promotion when basically nobody's mom is going to want neon electronics?
So, keep an eye out for some ad circulars if you're interested in seeing this bundle become reality, but don't hold your breath. While Nintendo does do exclusive seasonal bundles through GameStop on a regular basis, marketing a Lime Green DS Lite for Mother's Day just strikes me as too tone deaf on Nintendo's part.
EDIT: Moved this out of Speculation and into Nintendo News because I just got confirmation from my local GameStop's manager that this is definitely happening and the bundle is already in their ordering systems.
