You are wrong you do need it for FC6 as posted here.
Any x86_64, or ia64 CPU is supported for running para-virtualized guests. To run i386 guests requires a CPU with the PAE extension. Many older laptops (particularly those based on Pentium Mobile / Centrino) do not have PAE support. To determine if a CPU has PAE support, run the following command:
$ grep pae /proc/cpuinfo
flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 mmx fxsr sse syscall mmxext 3dnowext 3dnow up ts
The above output shows a CPU that does have PAE support. If the command returns nothing, then the CPU does not have PAE support.
New PAE Requirement for i386 Guests. Previous versions of the Xen kernel did not require PAE support. This change will affect laptop users
