I just did, and ran into 2 things, 1st being an oops or crash that stopped 
the shutdown and I was forced to use the hdwe reset button.  I rebooted to 
2.6.32.3 which worked nominally correct, then to 2.6.33-rc3 again, and played 
10,000 monkeys on the keyboard while it was sitting there waiting for the 
/lib/firmware/amd-ucode/micrococode_amd.bin for 60 seconds, with no apparent 
effect.

I am not convinced my wireless keyboard is alive at 0.6 seconds into the boot 
procedure.  Or I was using the wrong key for 'sysreq' as susch a labeled key 
does not exist on this logitek cordless keyboard.

What line in the .config file actually specifies the path it is supposed to 
be searching to find this file?

>From a grep FIRM .config:

CONFIG_PREVENT_FIRMWARE_BUILD is not set
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="radeon/R100_cp.bin.ihex  radeon/R200_cp.bin.ihex  
radeon/R300_cp.bin.ihex  radeon/R420_cp.bin.ihex  radeon/R520_cp.bin.ihex  
radeon/RS600_cp.bin.ihex  radeon/RS690_cp.bin.ihex"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware/"
CONFIG_LIBERTAS_THINFIRM=m
CONFIG_LIBERTAS_THINFIRM_USB=m
CONFIG_HOSTAP_FIRMWARE=y
CONFIG_HOSTAP_FIRMWARE_NVRAM=y
CONFIG_FIRMWARE_EDID=y
CONFIG_FIRMWARE_MEMMAP=y

Is something missing above?

If I want to add the amd-ucode/microcode_amd.bin to CONFIG_EXTRA_FIRMWARE, I 
will have to do it by hand as the xconfig editing function for that line 
seems to have gone away.  That list of radeon stuff hasn't been touched in 
nearly 2 years.  However, I will do that and report eventually.

Or did the firmware loader itself get broken?

Thanks Jiri.
