Radiohead - How Can You Be Sure Chords

How can you be sure?  by Radiohead

From the "High & Dry" CD single... played at a deliberate, medium tempo.
The bass actually echoes most of the melody in the song, so it can sound a
little wack on an acoustic guitar. Try walking the E up to the A on the
"good things and bad" parts to fill things out a little bit.

Verse:
  E    B   E           A2->A
  Seen all good things and bad
  E       B    E   A2
  running down the hill
  E   B  E            A
  All so battered and brought to the
  E       B  E   A2
  ground
  E B  E      A2->A
  I am hungry again
  E    B     E     A2
  I am drunk again
  E        B   E       A
  With all the money I owe to my
  E    B   E
  friends

Pre-chorus:
  A    G#m F#m  E5
  When I'm like this
  B       A      G#m      F#m
  How can you be smiling, saying

Chorus (inhale deeply!):
  E  B E A
  Ho-o-w can you be sure?
  E  B E A
  Ho-o-w can you be sure?

Verse:
  If you walk out that door, will I see you again
  if so much of me lies in your eyes?
  I am hungry again, I am drunk again
  With all the money I owe to my friends

Notes on the chords:

I'm not sure what to call the B that I hear in the song, but I think it
might be a B5. It's fingered thusly; essentially just a power chord.
e--X---
B--0---
G--4---
D--4---
A--2---
E--X---

Also, the A2->A is accomplished through a hammer-on, like so:
e--0---2-2
B--0---0h2
G--2---2-2
D--2---2-2
A--0---0-0
E--0---0-0

I think the G#m employed in the chorus is played with some open strings:
e--0
B--0
G--4
D--6
A--6
E--x

And finally, the E5 in the chorus is played like an open D, but barred up 2
frets (kinda like how you might play an Eb)
e--x
B--5
G--4
D--2
A--2
E--0
