Ubuntu does not detect wifi/bt combo card BCM4330 (AP6383)
Promethean, I got it to work after about two weeks of trying and getting help from broadcom and intel hackers. The more verbose description is at blog post, but here's the gist:
ACPI is currently broken, so WiFi is switched off. Confirm by issuing
# cat /sys/bus/acpi/devices/INT33BB\:00/power_state
D3cold
so enable it using
# echo on > /sys/bus/platform/devices/INT33BB\:00/power/control
Thats really all it takes! :) If you need firmware, copy brcmfmac4330-sdio.bin from linux-firmware to
/lib/firmware/brcm/brcmfmac4330-sdio.bin
Then get the NVRAM file from your windows driver and copy it to
/lib/firmware/brcm/brcmfmac4330-sdio.txt
Mine looked like this:

I got both STA and AP to work.
The power button is an ACPI issue. Mika Westerberg of intel created a patch against 3.19:
From 3404c6f2422c9e8d3f51a8832fbce01483c423d9 Mon Sep 17 00:00:00 2001
From: Mika Westerberg <mika.westerberg@...>
Date: Wed, 11 Feb 2015 17:21:18 +0200
Subject: [PATCH] pinctrl: baytrail: Relax GPIO request rules for certain pin
On Baytrail-T based machines the power button is part of GPIO keys like
button array (and implemented as a GPIO). However, Zotac ZBOX BIOS fails to
configure the pin properly which prevents the driver to request it.
Following is printed on the console:
byt_gpio INT33FC:02: pin 16 cannot be used as GPIO.
Fix this by relaxing GPIO request rules for this particular pin.

This makes the power button work. Mika said this patch would make it to mainline, but didn't want to confirm 3.20, as it would require some more work.
