    The code

The code for boot.s and linker.ld was taken from OSDev Wiki with no modifications. kernel.c is also heavily inspired by OSDev. The Makefile is mine. Yay!
The problems

There are actually two issues here.
It doesn't link

Using this particular linker.ld results in a linker error:

Kinda makes sense. This code from linker.ld:
. = 0xC0100000;
/* Add a symbol that indicates the start address of the kernel. */
_kernel_start = .;
.text ALIGN (4K) : AT (ADDR (.text) - 0xC0000000)
{
	*(.text)
}

...sets a weird load address (LMA) with the AT command. From GNU ld docs:

ADDR(section) Return the address (VMA) of the named section.

So because of . = 0xC0100000;, ADDR (.text) == 0xC0100000 since it's already page-aligned. Thus, ADDR (.text) - 0xC0000000 == 0x00100000, so we get AT(0x00100000).
But .multiboot.data is loaded at the same address, isn't it? ld tells me exactly that:
section .text LMA [0000000000100000,0000000000100049] overlaps section .multiboot.data LMA [0000000000100000,000000000010000b]

Shouldn't .text be loaded after .multiboot.text instead?
It triplefaults

If I put it after .multiboot.text, it links fine, but the resulting binary triplefaults.
/* Change linker.ld */
.text ALIGN (4K) : AT (ADDR (.text) - 0xC0000000 + __multiboot_end - 0x00100000)
{
	*(.text)
}

The file seems to be correctly linked:
$ objdump -h kernel.elf

kernel.elf:     file format ELF32-i386

Sections:
Idx Name          Size      Address          Type
  0               00000000 0000000000000000 
  1 .multiboot.data 0000000c 0000000000100000 DATA 
  2 .multiboot.text 0000006b 000000000010000c DATA 
  3 .text         0000004a 00000000c0100000 TEXT 
  4 .eh_frame     00000038 00000000c010004c DATA 
  5 .data         00000004 00000000c0101000 DATA 
  6 .bss          00006000 00000000c0102000 BSS
  7 .comment      00000011 0000000000000000 
  8 .symtab       000001f0 0000000000000000 
  9 .strtab       000000e7 0000000000000000 
 10 .shstrtab     00000053 0000000000000000 

$ 

So, .multiboot.data is at 0000000000100000, as expected, and .text starts at 00000000c0100000 - also as expected!
