check that you're running a kernel that knows about you cpu and its pm
and cpufreq features; check that you have 'performance' as default cpufreq
governor; put some bogomips(1) and/or
% cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freqtest
in key rc-scripts just to get trace of cpu state as boot goes on.
Perhaps the CPU didn't notice you've done power-on and keeps on sleeping ;)

Hello, can you post your dmesg and also the var/log/messages, because maybe
you have a kernel panic or saomething that stop the boot process.

On a few VAIOs you should turn off apic and lapic.

noapic nolapic

I've got a laptop Vaio with exactly that CPU and I've never had such a
problem of slow boot. I always use i686 kernels. With this computer
I've only had problems with the hard disk (SATA).
The exact laptop model is vaio VGN-A617B
