work-around can turn off adding line below /etc/default/grub , running update-grub:
grub_gfxpayload_linux=text
there upstream debian bug driver says if try use "vga=xxx" switch on linux 2.6.x kernel , driver, black screen. further says if use besides i915's driver's internal framebuffers, black screen. so-- "i915modeset=0" has set in kernel boot line turn off kms.
