This probably comes up once in a while, thought I'd raise it again.
I'd like to suggest switching the default kernel to -PAE on machines that support it, for the following reasons:
- many machines have 4GB+ these days, even desktops
- NX is only available with -PAE, improves security
- kvm is significantly faster on AMD when PAE is selected (since we
don't support NPT on non-PAE)
What's needed to set this by default is changes in anaconda. They have their own list at anaconda-list@redhat.com
Unless we keep the non-PAE i586 kernel around as a fallback, we're not going to be able to boot on a whole raft of crappy i386 chips (original Pentium M most notably...)
I'm not suggesting dropping non-PAE. Simply defaulting to PAE where possible.
Are Pentium Ms (really the memory that comes with them) actually capable of running recent Fedoras? I'm talking desktop, not I'm-using-my-laptop-as-a-firewall-just-because-I-can.
