well, I was surprised to find that machine is using mkinitrd (sid
box). I thought we had moved to yaird. regardless, there is a file for
mkinitrd, /etc/mkinitrd/modules that behaves just like /etc/modules,
so I imagine you could use 'blacklist usbhid' to keep it out of the
initrd. I know some similar conf exits for yaird.
