Re: installing 64-bit kernel on a 32-bit system

You can use 32 bit OS in 64 bit processor.

32 bit address bus will use 64 bit. MSB 32 bits will be idle..

But for the case, 64 bit OS in a 32 bit processor is not possible by theory.

I did not think that it will work. Also i did not tried this. Any one tried this combination and working fine?

A similar problem had been described for the Nvidia closed driver;
same thing with noveau? not a good thing: the kernel-X interface
is expected to be cleaner in the open source driver...
