See http://supermount-ng.sf.net/ and project page. The patch is for 2.5.70, it won't apply to earlier versions.
It needs quite a bit of work still but CD-ROMs (at least, IDE, I do not have SCSI) and floppy seem to work. If anybody desperately needs ide-floppy I could add it, but I'd rather wait until mediactl interface is stabilized. I'd prefer bug reports via tracker on sf but of course it is your choice :) -andrey
