This is the riff played repeatedly for most of the song (I can't be bothered to count 
how many times, sorry):

G|-----------------------------------------------------|
D|---------6-7----4-----------------6-7------------7-6-|
A|------------------2h3-4-3---2-222------555-6-7-------|
E|-2-222-------2-2-------------------------------------|

Then at 5:27 there is a brief break (only one repetition) that goes:

G|-----------------------------------------|
D|-------------------------------------7-6-|
A|---------------4-3-2-------555-6-7-------|
E|-2-----------2---------------------------|

After this, the regular riff is once again played (8 times). At 6:35, a slightly 
different pattern is played:

G|----------------------------------------------|
D|---------6-7----4-----4-6h7p6-4-----------7-6-|
A|------------------222-----------555-6-7-------|
E|-2-222-------2-2------------------------------|

Then after a few beats of drumming, it ends on a single note:

G|---|
D|---|
A|---|
E|-2-|

I'm about 97% sure this is correct. Listen to the song for exact timing.
