I was running stable with a lot of testing unmasked.  Then upgraded
to gcc-4.1.1 with an immediate emerge -s && emerge -e, which went
mostly smooth. 

Then decided to go ~x86 for the system.  That is where the pain was,
particularly expat which caused most of kde/gnome to need to be
upgraded.  Unfortunately a lot of the tools to do the rebuild also
depended on expat.  So it was update a few packages, rebuild a tool,
update a few more packages, ...  Lesson learned is when upgrading
to expat-2, immediately take the hours needed to do the
revdep-rebuild (in all honesty, I didn't see the ewarn message
because I was upgrading 448 packages).  It really would have been
nice if the expat-2 emerge package died after giving the instructions
to revdep-rebuild...

So far (5 days) the system has been real nice, no problems.  KDE
appears (subjective) faster (with USE=kdehiddenvisibility).  So +1 on
upgrading a ~x86 to gcc-4.1.1.

For those considering stable to testing, the main changes are
pam-logon/shadow (unmerge pam-logon), coldplug/udev (unmerge
coldplug), expat (revdep-rebuild), ocaml (dependent packages must
be manually rebuilt afterwards).

HTH,
