I'm using this patch these days: http://people.freebsd.org/~np/kgdb+kld+amd64.diff The changes to the kernel linker were not required originally. See this for why they had to be made: http://lists.freebsd.org/pipermail/freebsd-hackers/2009-November/030093.html The patch is quite crude and I have no idea how it behaves on other platforms.
