It would help if you provided a (minimal) sample file, but without  
that, I'll take a guess....

I think your fonts are being found just fine. (You get messages from  
fontspec because there are no corresponding bold and italic faces, but  
you can ignore these.)

The problem is that you're using \setmainfont to tell it what font you  
want to use. This configures the LaTeX "roman" font. But beamer  
defaults to using sans-serif, so it's ignoring your font and  
continuing to use Latin Modern Sans, which doesn't have any Ethiopic  
characters.

So you have two options: either use fontspec's \setsansfont to specify  
a new font for sans-serif, or tell beamer to use the default (normally  
serif) face instead by saying \usefonttheme{serif} in your document.
