Yes that is correct.

The correct value here is 51. I don't really understand why this value
is not a 8-bit one, as the memory access is done through ldub_phys().
Could you please verify that helper_ld_asi() is called with the correct
parameters. This should be 0x20 0x1 0x0.

PS: I don't know if I will be able to get internet access in the next 4
days.
