<M> EHCI HCD (USB 2.0) support
Wie sinnvoll ist es, in einem Kernel, der via USB sein Bootdevice finden soll, die Low-Level-Treiber als Modul zu bauen? Narf, narf, narf ;)
Wie geht der Spruch? »Kaum macht man’s richtig, funktioniert’s«? :)

Na, ok, fast ;) ext2 ankündigen, ext3 liefern ist ja auch unfair, irgendwie …
