Log Message:
- - Enable the cdrom driver, and begin to make it work on NetBSD.
    It can boot a Norton Utilities CD, but not run any of the
    utilities. That may be the known problem with the Windows 98 CD.
- - Add the ability, on NetBSD, to spin up the CD-ROM. This keeps
    "disklabel cd0" while booted from the NetBSD 1.5.3 rescue floppy
    from panicing the emulation, but it still doesn't return a label.
- - Go ahead and enable the network driver and dummy sound driver.
    The network driver almost works under the NetBSD  rescue floppy
    (ifconfig works, but not ping). I have no way, currently, of
    verifying the (dummy, silent) sound driver.
- - Bump to 1.4nb1.
