Cela veut dire que ton noyau est compilé pour une architecture minimale
bien précise : tu ne peux pas utiliser un noyau 586 sur une vraie
machine 386 ou 486 car le noyau incluera des instructions spécifiques
pour Pentium. Idem pour les autres architectures.

Tiré de l'aide des noyaux 2.4.x :

CONFIG_M386:

This is the processor type of your CPU. This information is used for
optimizing purposes. In order to compile a kernel that can run on
all x86 CPU types (albeit not optimally fast), you can specify
"386" here.

The kernel will not necessarily run on earlier architectures than
the one you have chosen, e.g. a Pentium optimized kernel will run on
a PPro, but not necessarily on a i486.

Here are the settings recommended for greatest speed:
 - "386" for the AMD/Cyrix/Intel 386DX/DXL/SL/SLC/SX, Cyrix/TI
   486DLC/DLC2, UMC 486SX-S and NexGen Nx586.  Only "386" kernels
   will run on a 386 class machine.
 - "486" for the AMD/Cyrix/IBM/Intel 486DX/DX2/DX4 or
   SL/SLC/SLC2/SLC3/SX/SX2 and UMC U5D or U5S.
 - "586" for generic Pentium CPUs, possibly lacking the TSC
    (time stamp counter) register.
  - "Pentium-Classic" for the Intel Pentium.
  - "Pentium-MMX" for the Intel Pentium MMX.
  - "Pentium-Pro" for the Intel Pentium Pro/Celeron/Pentium II.
  - "Pentium-III" for the Intel Pentium III
    and Celerons based on the Coppermine core.
  - "Pentium-4" for the Intel Pentium 4.
  - "K6" for the AMD K6, K6-II and K6-III (aka K6-3D).
  - "Athlon" for the AMD K7 family (Athlon/Duron/Thunderbird).
  - "Elan" for the AMD Elan family (Elan SC400/SC410).
  - "Crusoe" for the Transmeta Crusoe series.
  - "Winchip-C6" for original IDT Winchip.
  - "Winchip-2" for IDT Winchip 2.
  - "Winchip-2A" for IDT Winchips with 3dNow! capabilities.
  - "CyrixIII" for VIA Cyrix III or VIA C3.
  - "VIA C3-2 for VIA C3-2 "Nehemiah" (model 9 and above).

 If you don't know what to do, choose "386".
