ATI Radeon Driver Debian Packages

[Mark Schonfeld <mbschonfeld@gmail.com>]

I know about the page hosting debian versions of the ATI vid drivers
where you can either build from source or use pre-built binaries.  The
problem is when I follow the directions (either building from source
or using the prebuilt packages) I get an error at the end saying that
the module was not found (when I test to make sure it all completed). 
I've tried several times and think perhaps I'm not doing something
properly.  Does anybody know of a tutorial online for installing those
drivers, written in a style that somebody with limited Linux knowledge
can understand?  Thanks.
