I guess the easiest way would be to reinstall your whole system.

Off course it's possible, it is easier to reinstall though. See:

Changing the CHOST to your needs and doing as mentioned is not the whole story since there is more involved when switching from 64b to 32b.

Can you be more specific?

I'd buy another card. Less trouble, and those things are becoming dirt-cheap  |

Possible, yes. However, you will have to recompile EVERYTHING anyway. So, what's the downside of doing a full reinstall? It will take the same amount of time (just save the files under /etc on a tarball and then pick those that you need for the new install).
The dirty quick way to do it if you really feel so excited about not having to reinstall would be to uncompress a binary x86 toolchain (gcc, glibc, binutils, sandbox, python...), change your /etc/make.profile to point to an x86 profile, and your make.conf with the new cflags and chost settings, for that use the chost migration guide.
http://www.gentoo.org/doc/en/change-chost.xml
After that, compile an x86 kernel and then emerge -e everything.
Then, If something fails or there's some problem you reinstall anyway. |

It is certainly not that easy. Just think about that basic directories like /lib or /usr/lib are symlinks to directories which do not exist on a pure x86 install. |

Yep. The only way I can think of to ease that part is to uncompress an x86 stage on top of the actual install. That's why I said that there's absolutely no point in doing this. You are going to reinstall over your old install anyway (and in the way, you are going to leave lots of cruft and potential problems around), there's no easy way to make a clean transition other than reinstalling. |
