It is the symbol table for the kernel.  Entries are:

<address> <symboltype> <name>

[EMAIL PROTECTED]:~/linux-2.6.11/kernel> head /boot/System.map-2.6.10-1.741_FC3
00000400 A __kernel_vsyscall
00000410 A SYSENTER_RETURN_OFFSET
00000420 A __kernel_sigreturn

It's used for all kinds of things, including loadable modules.
