Installation: no Keyboard or Mouse

[kutte128]

Hi,

i updated my Gnome-PC to gnome 3 (with magneto/sulfur) wich worked just great.
but i couldn't use the Keyboard (usb and ps/2) and mouse (usb) anymore. i deinstalled the xf86-input-void and all went back to normal.

Now i try to install sabayon (daily 20110817) on a new box and also have no keyboard/mouse. this time they stop working using the installer.
i don't believe it's a bug because of the same problem after upgrading.

How can i use the Installer with keyboard/mouse?

sincerely,
