Comment 19 for bug 785394

ubuntu p/q/r/s/t versions of the source package show the same options:

./trusty/grub-0.97/debian/update-grub: extra_opts="$extra_opts crashkernel=384M-2G:64M,2G-:128M"
./raring/grub-0.97/debian/update-grub: extra_opts="$extra_opts crashkernel=384M-2G:64M,2G-:128M"
./quantal/grub-0.97/debian/update-grub: extra_opts="$extra_opts crashkernel=384M-2G:64M,2G-:128M"
./saucy/grub-0.97/debian/update-grub: extra_opts="$extra_opts crashkernel=384M-2G:64M,2G-:128M"
./precise/grub-0.97/debian/update-grub: extra_opts="$extra_opts crashkernel=384M-2G:64M,2G-:128M"

Which are from this changelog entry:
grub (0.97-29ubuntu24) intrepid; urgency=low

  * update-grub: Use a range of sizes when setting up crashkernel=
    - Less then 512M of physical memory, no crashkernel areas
    - 512M -> 2G use 64M for crashkernel
    - > 2G use 128M for crashkernel

debian's grub source package doesn't have this change.
