Here's how I play Vertigo (I think it's pretty close, I've studied Edge's technique on it inside and out).
The main riff is the D5 to E5 slide, of course. I use my 1st finger for the base note and my pinky for the 7th fret note, and I only play those two. I don't bother with the third string.
So when sliding I lagato-slide from the D5 to the E5 and pluck the E5 twice, and repeat.
Then when going from the A5 to G5, I incorporate strings 6,5, and 4 in normal fingering fashion. I hit the A5 three quick times (a quick down-up-down), strike once HARD on the Gsharp5 (either up or down), then finish with a quick down stroke on the G5.
