RELENG_8: amdtemp module and newer CPUs not working. MFC?

[Torfinn Ingolfsen]

Hello,
I'm running FreeBSD 8.3-stable on a machine with an AMD A8-5600K cpu.
tingo at kg-quiet$ uname -a
FreeBSD kg-quiet.kg4.no 8.3-STABLE FreeBSD 8.3-STABLE #2: Fri Jan  4 19:18:15 CET 2013 
    root at kg-quiet.kg4.no:/usr/obj/usr/src/sys/GENERIC  amd64
tingo at kg-quiet$ dmesg | grep CPU | head -1
CPU: AMD A8-5600K APU with Radeon(tm) HD Graphics    (3618.02-MHz K8-class CPU)

Unfortunately, the amdtemp.ko module doesn't work:
tingo at kg-quiet$ kldstat | grep temp
10    1 0xffffffff8123e000 f0f      amdtemp.ko
tingo at kg-quiet$ sysctl dev.amdtemp
sysctl: unknown oid 'dev.amdtemp'

Based on a thread[1] on the forums, amdtemp.c from -CURRENT work.
But it doesn't compile under FreeBSD 8.3-stable:

Are there any plans to MFC this module?
