It could well be more than 15-20 years since I had VESA FB enabled and not 
once since then, without any detriment to a console coming up at boot.  Try 
switching to [*] the following:

# CONFIG_SYSFB_SIMPLEFB is not set

# CONFIG_DRM_SIMPLEDRM is not set

# CONFIG_FB_SIMPLE is not set

Then hopefully you'll get a console kicking in.  Also, unless you use an 
initrd don't forget any firmware blobs which may be be needed by your graphics 
card and while you're at it add your CPU microcode there too.  Currently you 
only show the firmware for your wireless:

# Firmware loader
#
CONFIG_FW_LOADER=y
CONFIG_EXTRA_FIRMWARE="iwlwifi-6000-4.ucode"

Then, if you still fail to get a console, connect over ssh to check what dmesg 
reports for any hints of missing drivers.

HTH.
