Comment 4 for bug 47046

If you enforce reformatting of system partitions then please be careful. In my case above I was using /dev/sda10 only as a test install. There were still usable and wanted "real" 64bit system partitions on /dev/sda5 thru /dev/sda8 (sda9 is my swap on this drive).

My USB wireless card would not work at all with the RC amd64 installation so I was installing the regular i386 RC onto a spare partition on the same hardware to see if that would work with my wireless device (and it did, intermittently).
