If you have to ask the right answere is almost always woody and that
means 32 bit i386.

A real hybrid install, meaning multiarch, is absolutly pre alpha.
Nothing works there at all and it is purely for people developing
multiarch at this time.

A hybrid install with chroots on the other hand is perfectly
acceptable. You can try to install a 64bit base with all the little
quirks it still needs and see if that works for you and add 32 bit
stable chroots for things that need to be stable. Or you can do it the
other way around, install a 32 bit base and pure64 chroots to test out
new stuff.

The main question is: can you live with unstable/sid? Do you have the
knowledge and _time_ to handle it?

You should compile yourself a current 2.6 kernel for 32bit or download
the amd64 kernel-image and install that with -force-architecture.
Crosscompiling your own kernel isn't maintained anymore and bitrot has
probably made it break or even more cmplicated.

Do you want something that works or do you want to play around at the
bleading edge of developement?
