Yes, I've got new kernel sources, and yesterday and today I've spent
about 5 hours head-banging to get a working kernel.  (I've managed it,
thankfully.)  But the new kernel's X-windows isn't filling my 1920x1080
shiny new monitor like the old kernel did.  I've still got some fiddling
to do.

Call me a clinging cry-baby if you like, but until I'm confident about my
new kernel, I'd like to hang on to the old one, including its sources.
It'd also be nice to run --depclean in the meantime.  Do I have to do
recursive copying or directory renaming to achiev this?

As a matter of interest, do you know how to configure a framebuffer
console to fill up a wide screen (say, to a width of 170 characters) as
contrasted with the 128 characters which were optimum on an old fashioned
CRT?

OK.  I can manage that.
