You can use
,----
| #+OPTIONS: ^: nil
|
| * http://swift.siphos.be/linux_sea/
|
| 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: ^:{}
|
| * http://swift.siphos.be/linux_sea/
|
| a_{b}
`----
Only the a_{b} construct will undergo sub/super magic.
See section 12.3 "Export options" of the Org-mode manual.
