Most of x86-32 CPUs still in use support PAE. At least most of those installed on motherboards which can accept more than 4 GiB of memory. I do not call this an exception. I feel that x86-32 CPUs which do not support PAE are more the exception nowadays. >>> Yes, but there is also 32-bits PAE kernel that will allow you to use up >>> to 64 GiB of ram in your 64-bits CPU. >> >> PAE is a 32-bit feature.

I thought that in this paragraph you were talking specifically about PAE-capable processors, which can be 32 or 64-bit.
