Is there another patch or this is the latest one?
http://www.gelato.unsw.edu.au/linux-ia64/0405/9514.html

If that's the latest one, then it won't boot on any machine with nomca
parameter because once match found, it stuck in the for loop and memcmp
endlessly, cp never gets incremented :-(

How about this one:
