If you're still getting "target is synchronous" messages on bootup, then
the binpatch DIDN'T work. I've had some problems getting binpatch to
actually do its job and PATCH anything. It's really weird, and I don't
understand it, but I have to go through quite a rigamarole. Here's what I
did to get the patch to work:

binpatch -w -s _sbic_inhibit_sync -r 1 netbsd
binpatch -l -s _sbic_inhibit_sync=1 netbsd
binpatch -l -s _sbic_inhibit_sync -r 1 netbsd

The patch actually goes through on the second or third line. The secret
seems to be doing a word patch first, THEN a long patch. Don't ask me why,
that's just what works for me. If it works, you should see binpatch print
out a "1" as the value of sbic_inhibit_sync. Normally, it prints "0"
showing that the patch didn't take, even when you do it "correctly".
