I think that XeTeX will not hyphenate Kannada words because patterns for
the script do not exist. I am not sure about Sanskrit patterns. I am not an
expert but it seems to me that Sanskrit text can also be written in any
Indic script. The Sanskrit hyphenation patterns cover several scripts. I am
not sure whether Kannada is included.

rule prohibiting hyphenation before and after virama (ie inside the
conjunct) and between a consonant and an independent vowel. It seems to me
that the Sanskrit patterns were  created that way. Considering all the
sandhi rules for gluing the words together there is probably no other way
for Sanskrit.

Unicode-aware version. As Petr Sojka found some time ago, it may be useful
to set both lefthyphenmin and righthyphemin to 1 when generating the
patterns and use the correct values when typsetting.

switch hyphenation paterns in your document it is just necessary to assign
a proper value to \language. However, in LaTeX you would also like to have
localized texts for \chaptername, \contentsname etc. That's why its useful
to use some multilingual package. I would prefer polyglossia to babel.
Polyglossia is now maintained by Arthur Reuthenauer.
