Ah, good idea to check if it is NAND driver related or not.
But, it turned out that neither CONFIG_MTD=n nor CONFIG_MTD_NAND=n
did help (except that it spuriously turns the corner and boots).
So the only known factor so far is the offmode patch. But there must
be another one that differentiates between A4 and A5.
Something for the weekend to ponder on...
