This is the map of the early reservations (will send the dmesg + debug later):

[    0.000000] (6 early reservations) ==> bootmem [0000000000 - 00bbf90000]
[    0.000000]   #0 [0000000000 - 0000001000]   BIOS data page ==>
[0000000000 - 0000001000]
[    0.000000]   #1 [0000006000 - 0000008000]       TRAMPOLINE ==>
[0000006000 - 0000008000]
[    0.000000]   #2 [0000200000 - 0000d012b8]    TEXT DATA BSS ==>
[0000200000 - 0000d012b8]
[    0.000000]   #3 [00037dc000 - 00040fe2d9]          RAMDISK ==>
[00037dc000 - 00040fe2d9]
[    0.000000]   #4 [000009c800 - 0000100000]    BIOS reserved ==>
[000009c800 - 0000100000]
[    0.000000]   #5 [0000008000 - 000000b000]          PGTABLE ==>
[0000008000 - 000000b000]

As a side note: I've bigger older (2.6.26) kernels that boots fine,
and smaller 2.6.27 kernels that do not work, e.g. this one:

Overlapping early reservations b71000-effb43 RAMDISK to 200000-c84ecf
TEXT DATA BSS
