linux-image-2.6.15-53-amd64-generic 2.6.15-53.75 (amd64 binary) in ubuntu dapper

 This package contains the Linux kernel image for version 2.6.15 on the
 x86_64 architecture, the corresponding System.map file, and the modules
 built by the packager. It also contains scripts that try to ensure that
 the system is not left in a unbootable state after an update.
 .
 If you wish to update a bootdisk, or to use a bootloader to make
 installing and using the image easier, we suggest you install the latest
 fdutils (for formatting a floppy to be used as boot disk), and LILO, for a
 powerful bootloader. Of course, both these are optional.
 .
 Kernel image packages are generally produced using kernel-package,
 and it is suggested that you install that package if you wish to
 create a custom kernel from the sources.
