I just tried a beamer presentation I have with Lucida. I used:

\documentclass[color={dvipsnames,usenames}]{beamer}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage[T1]{fontenc}
\usepackage[expert,altbullet,lucidasmallscale]{lucidabr}

and everything works very nicely accept that accents seem to all be  
broken (for me, it is dots and hats). As Leslie Morland observed,  
this also includes bars and tildes. I am not sure what is going on  
here. It does the same thing even if I don't load the AMS packages.  
Now, if you remove:

\usepackage[T1]{fontenc}

it looks good, except that the fonts are no longer sans serif. It  
must have something to do with the way beamer is redefining fonts to  
make everything come out sans serif (I am in over my head there).

I wish I could help more, but it sounds like this needs to be taken  
to the author of beamer. I have cc'ed this reply to Till Tantau in  
hopes that he will reply with some insight.

Regards,
