TL;DR: Yes, it fixes it (for 2 of my laptops, at least).

Details:
Laptops were running (e.g.):

FreeBSD 15.0-CURRENT #155 main-n270400-02d15215cef2: Sat May 25 14:19:27 UTC 2024     root@g1-70.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1500018 1500018

After updating sources to main-n270407-73eb53813fe3 and doing a normal
in-place source-based update (which owrked, as such), I (attempted)
rebooting, which exhibited the previously-documented failures.

I rebooted using the kernel from main-n270400-02d15215cef2, applied the
patch, rebuilt the kernel, and ... the reboot this time was successful:

FreeBSD 15.0-CURRENT #157 main-n270407-73eb53813fe3-dirty: Sun May 26 13:02:07 UTC 2024     root@g1-51.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1500018 1500018

(My 3rd "development" machine -- the fastest one -- is still bogged down
with Yet Another Chromium Rebuild on behalf of production machines that
are due to be updated once that completes.)

Thanks!

Peace,
david
