Thing is, CRYPTO_AES on only selectable on x86.

 You're thinking about CRYPTO_AES_586.  But looking at crypto/Kconfig, 
 the dependencies are a bit weird:

 config CRYPTO_AES
          tristate "AES cipher algorithms"
          depends on CRYPTO && !(X86 && !X86_64)
 config CRYPTO_AES_586
          tristate "AES cipher algorithms (i586)"
          depends on CRYPTO && (X86 && !X86_64)

That's pretty broken, isn't it?

Would be better to just do:

config CRYPTO_AES
	select CRYPTO_AES_586 if (X86 && !X86_64)
	select CRYPTO_AES_OTHER if !(X86 && !X86_64)

and hide CRYPTO_AES_586 and CRYPTO_AES_OTHER from the outside world.
