 From the video, this happened just after i815drmkms attached.

   pci0 at mainbus0 bus 0  configuration mode 1
   pckb0 at pci0 [blur] 0 function[?] 0: vendor 0x8086 product 0x2770 (rev. 0x02)
   agp0 at [blur]: i815-family chipset
   agp0: detected 764k stolen memory
   agp0: aperture at 0x[blur], size 0x1[blur]
   i815drmkms0 at pci0 dev 0 function 0: vendor 0x8086 product 0x2772 (rev. 0x02)
   drm: Memory usable by graphics device = 256M
   drm: Supports vblank timestamp caching Rev [blur] (21.10.2013[?])
   drm: Driver supports precise vblank timestamp query.
   i815drmkms0: interrupting at ioapic0 pin 16 (i9[?]15)
   drm: initialized overlay support
   drm boot[?] error: [blur] [blur]

 at which point the screen blanks.


 ...so, you can probably install by disabling i815drmkms0, as follows:
  - select "boot prompt" from the bootloader menu
  - do "boot -c" for manual configuration
  - at the prompt there type "disable i815drmkms"
  - then continue/exit (c? q? I forget, sorry)
  - at that point the kernel should boot

 and once you have the system installed it will be much easier to try
 out proposed fixes for the i815 driver.
