(1) I don't see ALT_MEM_K used anywhere in setup.c if STANDARD_..._CALL
is defined.
(2) Your solution with patching setup.S to set PARAM+0x1e0 to zero is
better, because we can remove the STANDARD_..._CALL ifndef from setup.c
completely.
Anyway, thanks for reporting the problem -- I don't use the old way
of detecting memory anywhere, so I didn't catch the bug before...
Have a nice fortnight
