Installing linux-crashdump doesn't touch grub config

[Ralf Hildebrandt]

According to https://wiki.ubuntu.com/Kernel/CrashdumpRecipe, merely installing linux-crashdump would setup the system in a way suitable to create kernel crashdumps. At least I'm guessing this, since the latest version mentioned there is 10.04 while I'm at 11.04.

I rebooted after installation and don't find any crashkernel settings:
