[OT?] is there no package containing the raw "vmlinux" kernel image?

  great, thanks, i'll check that out, but let me (reluctantly) drag
this out for one most post since i think i found what i want.

  to recap (and sorry for boring folks with what are trivialities
relative to what normally happens on this list), i'm updating a lesson
on how to debug a running kernel and loadable modules with simple gdb,
and that requires both access to /proc/kcore and a raw vmlinux file
that corresponds *exactly* to the running kernel.

  if a student of mine can rebuild a new kernel and reboot, then it's
trivial.  but in some cases, i know some of my students *don't* have
the freedom to reboot the system to get to a new kernel -- they can,
however, download source and configure and build to get a vmlinux file
that (ideally) would match the running kernel.

  from reading:

https://help.ubuntu.com/community/Kernel/Compile

all i really want is to download the source tree that was used to
build the running kernel:

$ uname -r
2.6.32-22-generic
$

at which point i can simply configure based on the appropriate
/boot/config file and build, does that make sense?

  i installed what *looked* like an appropriate kernel source file:

$ sudo apt-get install linux-source-2.6.32

that gave me a kernel source tar file, i unloaded it and now i have a
source tree.  but the actual info is:

  ii  linux-source-2.6.32     2.6.32-23.37

which doesn't exactly match my current kernel.  so ... long story
short, all i want is the pristine, unconfigured source tree that
matches my current kernel, and i'm pretty sure i can take it from
there.  i apologize if i'm making this harder than it has to be.

  i'm not *trying* to be dense about this, i am merely succeeding.
