FreeBSD 9.1-beta1: amdtemp.ko and AMD Fusion chips

I recently upgraded a AMD Fusion machine[1], to FreeBSD 9.1-beta1.
I was a bit surprised to see that the amdtemp.ko module didn't work for this machine,
as I thought PR kern/156358[2] had fixed that. Perhaps it didn't get in in time for 9.1?
Anyway, I installed latest sources, used the patch found in the forums[3] and built a new kernel, and now amdtemp.ko works:
tingo at kg-f4$ uname -a
FreeBSD 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #1: Sun Aug  5 18:43:08 CEST 2012     root at  amd64

 2    1 0xffffffff81521000 3048     amdtemp.ko
tingo at kg-f4$ dmesg | grep amdtemp
amdtemp0: <AMD CPU On-Die Thermal Sensors> on hostb4
tingo at kg-f4$ sysctl dev.amdtemp

dev.amdtemp.0.%driver: amdtemp
dev.amdtemp.0.%parent: hostb4
dev.amdtemp.0.sensor0.core0: 54.0C

Perhaps someone could MFC a patch?
