Subject: Wrong path for ucode in udev

Hi...

I'm trying to see if my CPU needs an ucode update or not.
I want to see if I get positive feedback from the kernel, but I see a couple
problems:

- I hacked the firmware.sh script with a couple debug lines:

logger "$DIR/$FIRMWARE"
logger /sys$DEVPATH

And i get this:

Nov 17 17:01:53 bran logger: /lib/firmware/intel-ucode/0f-02-09
Nov 17 17:01:53 bran logger: /sys/devices/platform/microcode/firmware/microcode

In that second path, firmware.sh looks for /data, /loading, etc.
The problem is that path _doesn't exist_.
Is firmware.sh out of date ? Or the kernel is missing something ?

- The kernel does not give any info about successful load, even when microcode_ctl
  writes to /dev/cpu/microcode (as the split files still do not exist...)

Any ideas ?

kernel is 2.6.31.6, udev is 147.

TIA
