Boy, I hate straying from portage when I don't have to... makes  
upgrading such a pain... but... if that is what it takes, I'll give it  
a shot.
(btw, I did use a newer kernel, cuz there is no 2.6.21 in portage  
right now, and like I said, I try to stay with the package manager  
where possible.)
Thanks for the input here, Mike.  I'll give your suggestion a try.   
I'll post back with results..
