It looks like we're making progress.  I pulled your change.  The 
above *ERROR*, now become


info: [drm] Loading CAICOS Microcode
error: [drm:pid110:ni_init_microcode] *ERROR* ni_cp: Failed to load firmware "radeon/CAICOS_pfp.bin"
error: [drm:pid110:evergreen_startup] *ERROR* Failed to load firmware!
drmn0: error: disabling GPU acceleration
drmn0: warning: 0xfffff80007168400 unpin not necessary
drmn0: warning: 0xfffff80007168400 unpin not necessary
error: [drm:pid110:evergreen_init] *ERROR* radeon: MC ucode required for NI+.

It looks like radeonkms.ko is looking for the firmware in
a subdirectory of /boot/modules, namely, /boot/modules/radeon.
But, I have
/boot/modules/radeon_CAICOS_mc_bin.ko*
/boot/modules/radeon_CAICOS_me_bin.ko*
/boot/modules/radeon_CAICOS_pfp_bin.ko*
/boot/modules/radeon_CAICOS_smc_bin.ko*

Note, /boot/modules/linker.hints contains

radeon_CAICOS_mc_bin_fw
radeon_CAICOS_mc_bin.ko8
radeon_CAICOS_mc_bin_fw
radeon_CAICOS_mc_bin.ko4
radeon_CAICOS_me_bin_fw
radeon_CAICOS_me_bin.ko8
radeon_CAICOS_me_bin_fw
radeon_CAICOS_me_bin.ko8
radeon_CAICOS_pfp_bin_fw
radeon_CAICOS_pfp_bin.ko
radeon_CAICOS_pfp_bin_fw
radeon_CAICOS_pfp_bin.ko
radeon_CAICOS_smc_bin_fw
radeon_CAICOS_smc_bin.ko
radeon_CAICOS_smc_bin_fw
radeon_CAICOS_smc_bin.ko

while /boot/kernel/linker.hints for base drm2
appears to have

radeonkmsfw_CAICOS_mc_fw
radeonkmsfw_CAICOS_mc.ko
radeonkmsfw_CAICOS_mc_fw
radeonkmsfw_CAICOS_mc.ko
radeonkmsfw_CAICOS_me_fw
radeonkmsfw_CAICOS_me.ko
radeonkmsfw_CAICOS_me_fw
radeonkmsfw_CAICOS_me.ko
radeonkmsfw_CAICOS_pfp_fw
radeonkmsfw_CAICOS_pfp.ko@
radeonkmsfw_CAICOS_pfp_fw
radeonkmsfw_CAICOS_pfp.ko

Don't know if this will cause a problem.
