i915drmkms and intelfb in the kernel

i915drmkms0 at pci0 dev 2 function 0: vendor 8086 product 5912 (rev. 0x04)
i915drmkms0: interrupting at ioapic0 pin 16 (i915drmkms0)
intelfb0 at i915drmkms0
intelfb0: framebuffer at 0xffff8380676fc000, size 1280x1024, depth 32, stride 5120
wsdisplay0 at intelfb0 kbdmux 1: console (default, vt100 emulation), using wskbd0

That's the video-console version.  The serial-console version is

i915drmkms0 at pci0 dev 2 function 0: vendor 8086 product 5912 (rev. 0x04)
i915drmkms0: interrupting at ioapic0 pin 16 (i915drmkms0)
intelfb0 at i915drmkms0
wsdisplay0 at intelfb0 kbdmux 1

Well, this could be related, but the HDMI ports don't seem to work
either in my case.

What would be involved in switching to genfb?  Just disable i915drmkms,
or is there more to it?
