So maybe I am doing something wrong, or I have something broken in my 
kernel. Here is the command line I used:

qemu-system-arm -M versatilepb -kernel vmlinuz -initrd initrd.gz -append 
"root=/dev/ram console=ttyAMA0" -nographic

The kernel and the initrd are available on http://temp.aurel32.net/arm . 
The initrd is actually the one from the debian-installer. To get a 
console, select "Go Back" to get a menu where you can select "Execute a 
shell".

I have compared QEMU 0.8.1, QEMU 0.8.2 and QEMU CVS, both on an i386 and 
an amd64 machines. Versions 0.8.2 and CVS are a lot slower than version 
0.8.1, even for booting the kernel.

It would be nice if somebody could do the same tests, to make sure it is 
not related to my machines.

Thanks,
Aurelien
