Maybe, maybe not...

   However, since last June AMD decided to activate the 64-bit
extensions on socket 754 Sempron processors. Because of that there are Sempron processors in the market that have these instructions and processors that don___t have them. How can we detect if a Sempron CPU has the 64-bit instruction

I wouldn't be surprised if Debian-amd64 ran on my box.
