If you give me a hint what to do and where to look, I try to fix it,
because at the moment kldload does not work for the more interesting cases
(ethernet drivers that need mii and netgraph) and I need this because I'm
trying to get NgATM running on sparc.

Not that I want to dissuade you from fixing kldxref, but you can just
kldload the modules by hand, or compile them statically into your
kernel.

If you are updating from -current before Nov. 6th please be sure to use
make buildkernel after buildworld so that the new assembler is used to
build the kernel. These mnemonics are not recognized by gcc from before
that date.

Netgraph cannot be loaded by hand because of the private namespace between
dependend modules (a symbol not explicit exported but global in a module
can be seen only by other modules if loaded via a dependency). Compiling
into the kernel is hardly an option if you are going to fix things taking
into account compile times on sparc.
