Install SL on Sony Vaio

Guys, i´m trying to install OS X on my Sony Vaio (VPCSB25FB) since last month with no success.

I´ve tried iboot, iboot legacy and a lot of versions of OS X (snow leopard, lion, Atkos L2, S3,...)

Yesterday i think it was the closest i got from succeed.. i´m using iboot legacy and original DVD of snow leopard.
but i´m getting a kernel panic.

Could you pleeeeeease help me? I don´t know what to do anymore...

I´ve attached the error message and my configuration as shown on CPUz.

Thanks to all!!
