Not knowing Kannada, I don't know the answer to the following  
question: does Kannada use mere phonetical patterns or etymological  

In the first case, things are pretty simple. You might want to reuse  
the Kannada block in hyph-sa.tex (attached below). It is meant for  
Sanskrit written in Kannada script, but if Kannada also follows  
phonetical patterns most rules should be the same. The syntax is  
simple too:
--- 1 means "you may break in this position";
--- 2 means "you may not break in this position";
--- . means "beginning of word" before a character or a sequence of  
characters, "end of word" after a character or a sequence of characters.
Of course, you may have to delete some rules which apply in Sanskrit  
but not in Kannada, or to add some rules which apply in Kannada but  
not in Sanskrit.

In the second case, it is much more work. You will have to use  
patgen, about which you will find informations here:
It means you need a Kannada electronic text (as long as possible, to  
have as many word forms as possible), from which you will create a  
list of word forms (a way to do this is to convert each space to an  
end-of-line character, then to use "sort -u"); you will have to  
hyphenate those word forms manually, then to run patgen on the list  
to create hyphenation patterns. But since patgen does not support  
Unicode, you will have to use some kind of ASCII representation of  
Kannada, and to convert the resulting patterns into Unicode. There is  
an opatgen, which supports Unicode, but it does not seem to work that  

Best wishes,
