Yup.  There are a couple others out there, too.
I haven't switched to using them because
a) the kernel headers work fine, and unpacking the linux
   kernel sources really isn't that big a burden
b) I'm not convinced they work for all architectures (e.g. whacky
   combinations of embedded processors and their options)
c) I think they all assume you're trying to support linux-2.6,
   so if someone wants to do a linux-2.4 only
   system, they might object to the linux-2.6 abi leaking in
   via these headers
I think they're a good idea, just not quite yet for crosstool.
