Hi everybody,

Now Iberê has verified that fake-PAE works with a Celeron M 1.2 GHz.
Lubuntu 13.04 is installed and the data has been shared to make the span
of Pentium M and Celeron M CPUs wider.

-o-

Our test results so far for Pentium M CPUs suitable for fakePAE, 'No PAE
flags but 36 bit physical memory address size':

        --- CPU name ----  -- CPUID Output of 'cpuid|grep ^00000001' --
Lowest: Celeron M 1200 Mhz 00000001 00000695 00000812 00000000 a7e9f9bf
        Celeron M 1.40 GHz
        Pentium M 1.50 GHz 00000001 000006d6 00000816 00000180 afe9f9bf
        Pentium M 1600 MHz 00000001 00000695 00000816 00000180 a7e9f9bf
Highest:Pentium M 1.70 GHz 00000001 000006d6 00000816 00000180 afe9f9bf

Best regards
Nio
