   Problem #1 "solved" (worked-around). It looks like RB_KDB isn't being
passed over to the kernel properly. I simply commented out "if
(boothowto & RB_KDB)", and how have a kernel which actually waits for a
remote debugger to attach on boot.

   I enabled DEBUG_KGDB, and when I attach the debugger from the
"remote" the target clearly reacts to it. Unfortunately, the "remote"
says "PC register not available" -- and it doesn't appear to actually be
connected.

   Is kgdb supposed to work on amd64 and/or -current? I'm starting to
get the feeling that this is somewhat untested.
