Is it normal that X consumes 800 MB RAM?

The longer the system runs, the more RAM X eats.  After about 5 hours of 
uptime, I get this:

That's about 800MB memory usage.  It gets worse as time passes.  Is this 
normal?  This looks like some memory leak to me.  Does the graphics 
driver play a role here?  I'm using AMD's binary blob for ATI cards (the 
"radeon" driver doesn't support my card.)  Anything else that might be 
going on?

This is on a Gentoo AMD64 system with X server 1.6.5, AMD Catalyst 9.11 
drivers and kernel  DE is KDE 4.3.4 (in case it matters.)
