Thanks. Its sometimes helpful if native English speakers helps out here. I 
have to admit that I don't really get the difference of both versions you 
mention above. In this sentense I refer to Linux board ports which need 
*additional* fixes in Linux. I'll send the changed patch in a few minutes 
with this sentence:

"
Only Linux board
ports in arch/powerpc with bootwrapper support, which recalculate the
memory size from the SDRAM controller setup, will have to get fixed
in Linux additionally.
"

I hope its clear now.

Best regards,
Stefan
