Careful with that word 'dis-pepsi' Oldschool. I had heard that a lawsuit was threatened against the band Negativeland for using that as a album title. I guess that it didn't happen though. This is from the Negativeland website:
"Fearing trademark problems (as advised by five volunteer lawyers), the DISPEPSI title does not appear anywhere on or inside the release. A sticker on the original pressings of the disc instructed buyers to phone a "word of mouth line" to learn the actual title. Three months after the release of DISPEPSI, however, PepsiCo officially stated that it had no intention of ever taking legal action against Negativland for trademark or copyright infringement, so Negativland began using the actual title in press releases and on this website. CD packaged with One World Advertising fold-out. No personnel listings."

All this came about after their lawsuit from their earlier 'U2' album. I've seen that cd in catalogs and is described as "the original banned, destroyed disc". appearently the lawsuit did't go too well for the band.
I did find a couple of short discriptions of the 'U2' cd here:
