lm32: revert to the old kernel, which boots up with lpj set via append

Bootup until a hello world:
[    0.000000] BINFMT_FLAT: Loading file: /init
[    0.000000] Mapping is 47438000, Entry point is 44, data_start is 1f00
[    0.000000] Load /init: TEXT=47438040-47439f00 DATA=47439f20-4743a0f0 BSS=4743a0f0-4743c130

Stopps here. :(
