Lenny: which arch for a Intel Core 2 Duo?

[Mirto Silvio Busico <mirtosilvio.busico@fastwebnet.it>]

Hi all,

my new notebook is an Acer AS5930G which uses an Intel Core 2 Duo cpu.

I should like to install the 64 bit version of Lenny.

Which is the correct arch for this processor?

Thanks
    Mirto

P.S. from http://cdimage.debian.org/cdimage/weekly-builds/ I downloaded the

amd64 kde CD

But, during the installation all went wrong:

    * normal graphic intall loops trying to detect the keyboard
    * expert graphic install goes on until it reaches the disk
      partitioning, then freezes
