Which installer?  The (USB) .img uses GENERIC kernel while the .iso
will uses INSTALL kernel IIRC.

INSTALL kernel has drmkms disabled so trying to boot a GENERIC kernel
is probably worth.

You can probably safetely do that by extracting the GENERIC kernel, e.g.
via:

 % cd /tmp
 % ftp 'http://cdn.netbsd.org/pub/NetBSD/NetBSD-9.0_RC1/amd64/binary/sets/kern-GENERIC.tar.xz'
 % tar xJf kern-GENERIC.tar.xz
 % su
 # cp netbsd /netbsd9

Then reboot and when in boot(8) do:

 boot netbsd9

(no modules should be needed to test that, but if in some ways they are
needed you can then also download the modules.tar.xz installation set
and do a `cd / && tar xJpf ../path/to/modules.tar.xz' to extract them
(they can cohexists with 8.0 ones))
