64-bit Semprons

So, during a conversation at PyCon UK, Keith White noticed that he owned the same model (HP nx6325) laptop as me. He also informed me that his processor was 64-bit, and asserted that mine probably was as well.

I was sceptical. It's a Mobile Sempron - last I checked, all Semprons were 32-bit. Of course, I don't keep up with hardware at all. Checking /proc/cpuinfo:

tim@regulus:~$ cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 76
model name : Mobile AMD Sempron(tm) Processor 3500+

bogomips : 1597.70

The 'lm' flag means 64-bit. So intuitive and obvious... so I guess that's one more thing to try when I get around to reinstalling my laptop.
