AFAICS, Debian mkinitrd does not automatically load the usbhid module,
needed to access the keyboard, and I don't see usbhid or the
prerequisite controller listed in the script listed earlier
in this report.

To work around this, add usbhid and ehci, ohci or uhci to
/etc/mkinitrd/modules; of course the more general kernel problem
may also exist.

If you're interested in adding USB kbd support to mkinitrd,
I'm working on a perl based alternative mkinitrd implementation
that handles USB keyboard.  The logic used there is not conveniently
expressed as a shell script, but as a rough approximation,

	if [ `ls -l /sys/class/input/event*/device | grep /usb | wc -l` != 0 ]
	then
		add usb_core, uhci_hcd, ohci_hcd, ehci_hcd, usbhid
	fi

should be mostly correct.
