Christophe,

building a kernel with distinct source and object trees I noted that
there is a consistent (but ignored) failure in generating the fore200e
firmware images. The problem is that in such a configuration there
simply is no include/asm link in the source tree. Consequently, a change
similar to the one below is necessary (this one's against a SuSE
derivate of 2.6.5, but checking with the 2.6.8.1 sources shows that the
relevant code doesn't seem to have changed).

Regards, Jan
