Hehe nice!

I also wondered about the resolution order :)

At least module dependencies can't be aliases.

Yeah, same happened to me.  Did the same (back then in "resolve-alias").

So should be fine.

Did it work before?  I remember that Andreas had a similar problem before all this.

Did you implement globs with [0-9] yet?  I remember there were some USB devices
using those :)

What's the modalias of your usb keyboard?

Does your initrd's modules.alias contain any patterns that are supposed to match?

(You can look into those via 
  cat initrd | gunzip -cd |cpio -i

- it will unpack)
