What is easiest way to chance amd64 version to x86? Just drop stage3 to top of current system and continue from there? I am upgrading proccessor and motherboeard from Pentium D 805 to Core Duo...

A stage 3 overwrite followed by a kernel recompile is akin to a new installation anyway.

Might as well reformat the old partitions.

Plus, all your intalled packages would need to be recompiled, since 32 bit and 64 bit binaries are not compatible. Probably.... emerge -e system followed by emerge -e world.... Though I'm sure there is more to it than that.

Best to back up your /etc/ and /home/username/, and do a fresh re-install....you are not going to be able to use any commands if you boot from a 32-bit kernel on a 64 bit system...

Can't format root partition, i need to save /home and /var/vdr/video. So i install according to handbook except no partitioning, just mount & rm unnecessary stuff.

Just thought if there were some fancy cross-compile option, just change make.conf and emerge world would be nice.
