Looks like Lucid gets the reservation correct (crashkernel=384M-
2G:64M,2G-:128M) as I see the following:
[0.00] Reserving 128MB of memory at 32MB for crashkernel (System
RAM: 9152MB)
Additionally, my system has now been generating crash dumps (and
rebooting) instead of simply freezing.

Andy's suggestion of crashkernel=384M-2G:64M,2G-:128M gets me a proper
reservation on 2.6.28-15-generic.

On my current setup this is using the following incantion, note that it
does not specify the location, can you see if that helps:
crashkernel=384M-2G:64M,2G-:128M

I've seen the same thing on my x86 Jaunty - updating the grub menu.lst
to where the argument for crashkernel is just crashkernel=128M seems
to fix the reservation problem.

I get such message Memory for crashkernel is not reserved everytime I
boot.

I am observing the exact same behavior. Same crashkernel argument, same
kernel, same arch, same distro, also nvidia nonfree kernel module.
