It might be easier to try and boot and install from a 6.1 amd64
CD-ROM. Then install your patches and build a new kernel+world.

Since all these work natively on amd64, I wouldn't use the i386
versions. Especially if you'd like to link programs to the KDE or
PostgreSQL libraries.

I'm not sure if you can link a 64-bit program to a 32-bit library and
expect it to work.

Make dumps of your partitions and back them up. If amd64 doesn't work
well enough you can easily restore your i386 system.
