Neither the kernel nor the bootloader support the floppy drive.  You could 
put the bootloader on a floppy and then boot the kernel and everything else 
from either a local scsi disk or from the network using NFS, but that would 
be silly (yet I tried it ;-))  

Working configurations are:
- bootloader on a TFTP server or on a local scsi disk
- kernel on a NFS server or on a local scsi disk
- filesystems on a NFS server or on a local scsi disk

Right now your best approach to getting started is following the INSTALL.* 
documentation and then moving parts to local disks if you like.
You should get a userland snapshot from:
ftp://releng.netbsd.org/pub/NetBSD-daily
and then a kernel from:
ftp://lola.pin.lu/pub/NetBSD/arch/next68k/scsi/scsi-06-06-current-05-20
(probably the netbsd-SCSI.gz one)
There's some SCSI specific information in the archives for this mailinglist.

If you need help getting started, feel free to ask...
