Okay, I listened to that segment of the solo, and I had some trouble with it myself... its basically three or four notes, but played in a succession that is a little tricky... let me see what I can do about finding you that passage... there is a little MIDI program called Power Tab that actually plays the songs in MIDI, the only problem being that it is still left up to the accuracy of the person transcribing the song, and there are some screwy tabs of songs out there....
EDIT: Okay, after looking the Power Tab versions of the song and recovering from being physically ill, I pulled out my old songbook, and the riff is transcribed on the high E string at the 15th fret, and as I suspected, it is basically four notes. I use the B string and go to the 19th fret and go for there, but it looks something like this:
E 15 14 15P12 15p12 15 14H15 12H15p12H15 14 15p12 15 12H15p14 15 12H15 12 15 14 15 12H15p14 15
B 12
E 12 15 12 14H15p12 15 12 15 14 12 15 12H15p14 15 12 15p12 15p12~~~~~

H are hammerons, and p are pulloffs, of course. Just by letting your fingers go you can make that part sound similar to the solo without being hyper accurate. After all, its someone else's interpretation of Adrian's solo. But its basically three notes with a fourth one thrown in near the beginning of that passage.
Hope this helps.
