It wasn't clear my previous mail: but the second cons refers to the
font name.  I used as an example the font "Arial Unicode MS": a TTF
font that came with Microsoft Office 2000.  Sorry about using an
non-free font as an example.

Try

  http://malayalamlinux.sourceforge.net/input-methods/
  http://malayalamlinux.sourceforge.net/input-methods/malayalam.ttf

(That site had no indication about the freedom of usage of the font.
So, the situation is not really much better.)

If there is no 'fonts.scale' file in that directory, create it with
the following contents inside the ---8<--- lines.

---8<--- fonts.scale
1
malayalam.ttf -misc-malayalam-medium-r-normal--0-0-0-0-p-0-iso10646-1
---8<---

If there's already a fonts.scale in that directory, add 1 to the
number on top of that file, and append the "malayalam.ttf -misc-...-1"
line to it.

Then run in that directory

  $ mkfontdir
  $ xset fp+ `pwd`
  $ xset fp rehash

Then, add the following to your .emacs:

      (set-fontset-font (query-fontset (frame-parameter nil 'font))
          (cons (decode-char 'ucs #x0D00) (decode-char 'ucs #x0D7f))
          (cons "misc-malayalam" "iso10646-1"))
