Well: patched, installed new serial_core.ko, then depmod -a, and try to
access ttySwhatever.

I don't see any difference... If I understood correctly, it could not load 
my 'fake' serial module anyway (?)

BTW. only changes,I think could affect serial directly and
     made betwen test9 and test10 are:

I could try to narrow it down to some -bk, but it will take time...

PS. I wonder - could it be, that somewhere in the middle of 
    decision process test9 > test10 (as test1something)
