I have a two part series that should be appearing in Circuit Cellar either this month or next, that is targeted very close to what you are looking for. You have to be a masochist to try to build linux kernels under cygwin. It is purportedly doable - I have never succeeded, but very painful.
If you must work under windows - I know alot of engineers do, then I would highly recommend colinux. www.colinux.org. It will give you linux and windows running concurrently on the same machine with very little pain, no additional cost, there is a small amount of grief getting windows-colinux networking functioning, that is not critical but it is nice. Getting X windows running is substantially more effort and is very nice - but completely unnecescary. Colinux is a much easier and lighter weight solution than virtualization. That said I would highly recommend you seriously consider doing linux development without windows. The targets you are going to be developing for are going to run linux. The initial learning curve might be steeper, but the payoff is greater. Everything you learn on the development side will apply to the target. There are bazillions of Live CD's you can try. I would highly recommend Ubuntu. Its alot like windows - except mostly friendlier and it works. Personally, I went the roll your own method for creating a development environment. I have no experience with ELDK. Buildroot and many other "environments" dictate a very specific way of working. They guide you to a working solution faster but I find myself fighting against their limitations all too soon. Unfortunately crosstools has not been updated in a while, and does not officially support uClibc (it does support glibc). uClibc is very appealing for limited resource systems. There is a crosstools-ng project, but it does not have ppc support. It would be really really nice (hint) if Xilinx would get their microblaze compiler code into the gcc distribution.
