Oh oh.  It was working.  I just tested this again:

9a079e65d14790c84cf931e9f50a3c945c15ddb8 drm/amdgpu: fix buffer funcs setting order on suspend
33cc938e65a98f1d29d0a18403dbbee050dcad9a (tag: v6.7-rc4) Linux 6.7-rc4

And it works, but 6.7-rc5 does not, even though it includes that patch.
Here's the syslog from the attempt.  I'll start bisecting again.
