Hmm, I just opened a jpeg in Lightroom 4 and the Lens Vignetting worked. Also the Post Crop Vignetting tool (in the Effects panel) worked. In fact the "effect" of the post crop tool was significantly stronger than the "normal" tool. You might want to give it a try!
I don't know about DPP, though, I see it's "off" with a jpeg...don't know why
And, welcome to POTN! And, congrats for having a great "Classic" camera!
Thanks. Yes, the Post Crop Vignetting tool does work, more or less. But, I have to mess with it. If I shoot raw, the Lens Profile-Vignetting thing just 'works'. Of the two options, I like the raw+Lens Profile thing better. It instantly corrects vignetting and distortion with little or no input.

If you shoot jpgs the PIC has already been done in the camera, so it would be pointless and excessive for DPP or LR to do it again automatically, even if it could. If you shoot Raw the PIC has not been done, only included as an item in the metadata list of camera settings which DPP sees and applies, but LR does not. However, the Lens Correction profile will do vignetting correction, but you have to enable it - for each photo or for all files by making it on by default or with a preset applied during import. LR contains more correction profiles for Raw files than for jpgs, but there are some for jpgs - I don't know if there is one for your lens.
Thanks for taking the time to answer, but I believe you are mistaken about PIC and the 5D. It is not capable of PIC, whether shooting JPG or raw. LR4.4 does have a profile for the EF24mm f/2.8 IS USM lens. It is only for .cr2 files, though. I can select a different lens, but the profiles don't match very well. This lens vignettes quite heavily at f/2.8.
