That would make sense. The ATI installer overwrites some OpenGL libs 
with it's own libs and if the package providing those libs within the 
distro subsequently receives an update then it will subsequently 
overwrite the ATI libs thus breaking the driver.

This is one of the advantages of using a properly packaged version of 
the driver - the ATI libs can then be safely installed to a location 
where they will not conflict with the distro libs and this type of 
situation can be avoided.
