You can use=20

,----
| #+OPTIONS: ^: nil
|=20
| * http://swift.siphos.be/linux_sea/
|=20
| a_b
`----

to turn off the super/subscript magic in the file (or customize
org-export-with-sub-superscripts to turn it on/off globally).

If you want to mix and match in the same file, you can use

,----
| #+OPTIONS: ^:{}
|=20
| * http://swift.siphos.be/linux_sea/
|=20
| a_{b}
`----

Only the a_{b} construct will undergo sub/super magic.

See section 12.3 "Export options" of the Org-mode manual.

HTH,
Nick
