You'll find various snapshots of 1.2Beta in various
places amongst others in ~ftp/pub/NetBSD/ports/i386/distrib-current
on which tries to make
a distribution on the 13th of every month.

Follow the instructions in NetBSD-1.1 INSTALL
and get the file-sets (for 1.2Beta base,comp,etc,text,misc...)

Yes if the kernels were compiled with compatibility
to NetBSD-1.1 but it's not a good idea when "release"
sets exist of 1.2Beta anyway, you'd also be missing
out on the bug/security fixes.

Given that installation floppies exist for
release 1.2Beta there is no need to patch
a NetBSD 1.1 floppy, but if you really want to...

If you want to replace an existing old kernel
with a new kernel you will need to compile
the new-kernel with the new source-files 
(and probably new gcc and binutils) remembering
the compatibility options COMPAT_10 COMPAT_11 
(and maybe COMPAT_09,COMPAT_NOMID if you still
 have very old files)

mount the floppies "mount /dev/fd0a /mnt"
and replace the kernel /mnt/netbsd with your
new one, you will probably not have enough
space as it's a 1.2MB-floppy-filesystem in 
which case you'll need to create a new 1.4MB floppy
and tar the files from the 1.2MB onto the 1.4MB.

see above.

It's small so it has as little options as possible
while still trying to support the most disk/net
configurations available. See sys/arch/i386/conf/INSTADP
