I caught that discrepancy on a re-read after my post came back from the list.
My card is housed in an HP Pavilion laptop model ZX5000 - fairly high end for
its time

Disabling composite was a 'fix' suggested by many sites for getting the ATI
driver going, which is why I set that - still haven't tried enabling it, yet

Personally, I don't care for Beryl - don't use it after giving it a try. I'm
in television production, and I use this box as an experimental platform for
trying the various LInux programs for content creation - so, that's my
interest

Having realized that I'm getting much better performance than I thought, I'll
probably just stick with fglrx for now, but I'll track the progress of the
radeon driver project, and give it another shot down the road
Thanks again for your input...
