There are far better ways to cross-compile the Linux kernel. I built a 
Cross Linux From Scratch system under Cygwin earlier this year. I just 
got back from vacation, though. Give me a day or so, and I'll find my 
notes on it. I believe most of them have already been posted here in the 
past, however.
