Doesn't help, I'm afraid.
I've seen this problem before and I never chased it down but when I saw
Nick Bell's idea, I figured that's got to be it. It *almost* works
but not quite (as Daniel found out).
If you enter /italic/ in an org buffer, place your cursor in there and
say M-x describe-text-properties, you get:
,----
| Text content at position 48:
|
|
| There are text properties here:
| face (italic)
| font-lock-multiline t
| fontified t
`----
You can then M-x describe-face italic <RET>. For me, that had
the :underline attribute set, and the :slant attribute unset.
If you customize the face, set the :slant attribute (e.g. to italic)
and unset the :underline attribute and *then* change to a font that
provides an italic form, then /italic/ is indeed italicized.
The problem seems to be in faces.el:
,----
| (defface italic
| '((((supports :slant italic))
| :slant italic)
| (((supports :underline t))
| :underline t)
| (t
| ;; default to italic, even it doesn't appear to be supported,
| ;; because in some cases the display engine will do it's own
| ;; workaround (to `dim' on ttys)
| :slant italic))
| "Basic italic face."
| :group 'basic-faces)
`----
which apparently looked at my default font[1], found that it does not
support italics but does support underlines and set the attributes
accordingly. *Why* it falls back to underlining is probably a question
that should be addressed to the emacs developers, but it looks like
a bug to me (hence copied to the emacs bugs list - version info appended[2])
HTH,

[1] I have
(set-default-font "-misc-fixed-medium-r-normal--15-120-100-100-c-90-iso8859-1")
in my .emacs. I think this is what used to be called "9x15" at some point in
the past, but I'm really not sure.
