Yep. Just switch your profile to the hardened one, and emerge system 
(the FAQ[1] claims only binutils, gcc, and virtual/libc are necessary). 
Then, switch your compiler, and emerge -ve world to recompile everything 
with the new GCC.

Note that I said there were *fewer* problems with gcc-4.x than there 
were with gcc-3.x hardened. That doesn't mean there aren't problems 
using hardened for a desktop machine. A few packages, e.g.

*  Non-free video drivers
*  Wine
*  Mplayer
*  OpenOffice

usually fail unless you switch to vanilla GCC temporarily. Although, now 
that gcc-4.x is stable, we can probably file these as bugs and get them 
fixed.
