Help! V3.3 Modprobe dies on boot with block-major-2 error, since my Desknote has no traditional floppy drive (uses a usb floppy - and it works).

Google indicates solution is "alias block-major-2 off" in modules.conf, so I installed to hard drive with Knoppix option so I could modify config files. Went to /etc/modutils/aliases as directed in modules.conf and inserted the above suggested entry. Makes no difference though. Same problem. Does Knopiix ignore the aliases configuration file, or set an otion elsewhere re modprobe instructions?
