Lenny kernel panic with 64 bit

[Valerio Pachera <sirio81@gmail.com>]

Hi all,
I just tried to run skolelinux-lenny with qemu-system-x86_64+kqemu on
a 64bit host and it give "kernel panic" right after I press "install
64".

In this moment I'm using the same qemu command but I chose "Install"
(32 bit) and the installation proccess is working.

My cpu is
Intel(R) Core(TM)2 Duo CPU     T5270  @ 1.40GHz
