drm2 deprecation in base: problems with gpu-firmware-kmod port

Hi there,

I've tried the kernel after drm2 bits were removed from the base to see
how they would be served by the ports.  This is on -CURRENT/i386 with
Radeon HD 4350/4550 (RV710) gfx card.  I've installed gpu-firmware-kmod
and drm-legacy-kmod ports, and rebooted into new kernel.  I don't use
kld_list="..." and only load a few modules from /boot/loader.conf, like
HDD controller and sound drivers, nothing gfx-related.

First thing I do after console login is "kldload radeonkms", had always
worked like a charm.  Now it's broken:

  ...
  info: [drm] radeon: 512M of VRAM memory ready
  info: [drm] radeon: 512M of GTT memory ready.

  error: [drm:pid16419:rv770_init] *ERROR* radeon: ucode required for R600+.
  drmn0: error: Fatal error during GPU init

I have this file with the previous kernel (when it all was in the base):

  /boot/kernel.june/radeonkmsfw_RV710_pfp.ko (11908 bytes).

With the drm2/firmware bits served from ports, the name is different:

  $ pkg info -l gpu-firmware-kmod | grep RV710_pfp
        /boot/modules/radeon_RV710_pfp_bin.ko

File size is also different: 10428 bytes.  How shall I proceed from this
point to get things back in working order?  Thanks,
