To continue this thread, I've gone to the brother site and found an 
installer script that pulled all the latest driver debs & what not, 
over-writing the original i386 installs with amd64 versions. That of 
course killed both the printer and scanner, But I still had, because I 
had pulled them manually Thursday, all the i386 versions too, so I 
opened the i386 versions of the debs with mc and clicked on the install 
script for each.  So the printer is back among the living but when I 
called up okular to finish the print job, it rendered in letter size, 
whereas the pdf interpretor used by mc apparently told it to format for 
A4, somewhat shorter and narrower than letter, so now I've a full 
printout that's a tad small for 139 pages, and jumps to a full letter 
sized render at page 140 by adobe count.  Its noticeably darker and much 
easier to read, with all the advanced color sliders set at 0. So even if 
the sliders still don't work, its good enough for most of my work, and 
its about 2 to 3x faster, which is nice.

One of the things I had noticed while snooping with wireshark a year or 
so back was that the first 6 wakeup packets sent had bad tcp checksums, 
then it started send god checksums, but just that caused a 7 second 
delay before it woke up.

But scanimage -l still can't find the scanner even with the i386 versions 
of its drivers re-installed.  Its address on the local net pings just 
fine, its the same as the printer, but sending FF to that address gets 
no mention of there also being a scanner at that same address.

I'll reboot in few to see if udev can find it.
 
Thanks everyone that tried to help, the printer is now running faster and 
better.
