Good question. Looks like it. I'm not very familiar with the >> no-execute stuff, but yes, I do believe it requires PAE. > > > Isn't this a rather significant feature regression? > Argh. This is an oversight on my part when bringing this as an option from the kernel team. I was not aware that the NX was dependent on PAE. The primary hardware that people were wanting all seemed to be below 4 GB so having PAE didn't seem to be worth the overhead. I am not sure if the OLPC desktops even have support for either NX or PAE. The people with P-III or no SSE2 definitely don't have PAE. -- Stephen J Smoogen.
