I have Dothan, it does not advertise PAE in cpuflags, but PAE kernel works.

No, my Dothan Pentium M (Family 6 model 13 with 400mhz bus) does not have PAE or NX in cpuflags.
NX is supported via kernel patch (see https://lists.ubuntu.com/archives/ubuntu-devel/2011-November/034502.html Dropping i386 non-PAE as a supported kernel flavour in Precise Pangolin - "This is about dropping non-PAE support, not dropping non-NX support. The NX emulation patch must remain in the kernel since a large number of systems have PAE but not NX.")

Fedora supports i686 kernels without PAE. The installer chooses to install a PAE kernel (or not) based on CPU and memory config - PAE capable systems with <4GB will get non-PAE kernel, as it is slightly faster and all memory is usable.
