It took me a while, but luckily I happened to read an old interview in a guitar magazine
in which Thurston talked about some of the tunings the band uses, mentioning the 
one in Disappearer.
Once I had the correct tuning, things were easier while trying to tab the song.
First of all, to anyone asking me "to tab this in standard tuning", that is not
possible, Sonic Youth (almost) always uses odd tunings, there's nothing I can do about 
On the other
hand I can help you achieve the desired tunings.

For this song, the tuning is gonna as follows:

D|--| (Standard high E, down one whole step)
G|--| (Standard B, down 2 whole steps. You can use standard B, if you want)
B|--| (Standard G, up 2 whole steps. You can let in standard G, if you want)
E|--| (Standard D, up one whole step)
C|--| (Standard A, up 1 and a half steps)
C|--| (At first I though this C was one octave lower than the other one but
       apparently it sounds better if they both are unisone, so it's up to
       you, you can either go up or down from the satandar low E)

Now you have the tuning, here's the tab.
