Maybe this is desirable, but breaking (irretrievably!) older systems is not so 
nice. There are many many lsb-less init.d scripts on my box.

I got rid of all the packages that need purging. I removed (not making much 
use of) all the fuse stuff which IS erroneously listed in this group--actual 
packages were uninstalled, not simply purging obselete init scripts!

Short of making a deboostrap chroot and moving all the scripts from there (if 
this would even do the job), what can I do?

I note that there are alternatives around to this sysv-rc system, i.e. file-rc 
(a flat, one level, no sym-link) and I recall seeing another alternative as 
well. Are these supported, deprecated, should be removed from the repo?

I enclose the list, edited from the console output by inserting new lines are 
required.

There are several item there that can be hand deleted. Knoppix stuff no longer 
used, kde3.5 no longer used, etc.

My x_oddsandends should be in local.rc (which I did know about when I wrote 
it).

The others seem to be normal inits from the packages. How would they get the 
need lsb info to correct the problem. I believe there are many more but that 
one big line ran out of space.

BTW, attempts to downgrade to testing package simply reinstall the Sid 
package.

The recommendation:
  dpkg --purge initscripts initscripts initscripts nut-server sysvinit

(The fuse items have been uninstalled.)

would be removing packages, not purging init.d files!
