Can't say much about iwm problems but Imre Vadasz just pushed big
wireless update to DragonFly master branch. You might have more luck
with it.

As for dual gpu setup you might need to disable integrated skylake
adapter in bios to have working radeon card, unless your bios(uefi?)
does that already.
I just got myself the Gigabyte R7 360 BONAIRE card and started playing
with it. Only card ID was missing in both kernel and xorg drivers.
Update xf86-video-ati to v7.7.0 was pushed into the DPorts so in a few
days it should be available as binary package once builders finish
rebuilding the tree.

The bug preventing to read EDID information from the monitor when
using Display-Port in DragonFly implementation of drm/radeonkms
aux/i2c was fixed in commit 8a140387ae41e85be4beaf0b2a7b90ab997d1c86
Previous to it using DP resulted in having just "generic" vga
resolutions like 1024x768, 800x600 etc and needed
drm.edid_firmware="edidfw_MONITOR" loader.conf tunable
to point to extracted EDID block firmware module for correct supported
video modes.
Keep in mind that DP port currently has few known quirks like re
plugging the cable keeps the connector in disconnected state.
So far I couldn't tackle it, DP support is a bit more complicated than
DVI/HDMI and any help on this would be very welcomed.

With Dragonfly master branch (think about it like a rolling release)
have tested DP on Radeon HD5770 and R7 360 cards.
Even an old JUNIPER hd5770 is able to handle 2560x1440 Dell monitor
at a native resolution when connected through Display-Port.
If I don't find any serious problems, R7 360 support will be
included in next DragonFly release.

Lets us know how it performs.
