/usr/src/distrib/amd64/cdroms/Makefile.cdrom

(1)
add 
 
CDRUNTIME+=     ./usr/libdata/firmware

or

(2)
(may be  wrong)
#CDKERNELS=     netbsd-GENERIC.gz       netbsd
CDKERNELS=      netbsd-INSTALL.gz       netbsd

because in INSTALL

# DRMKMS driver
no i915drmkms*     at pci?
no radeon*         at pci?
#no nouveau*       at pci?
