I too tried "device xhci" but it hung on boot in amd64.

For i386, non-generic kernel failed to build with xhci and even after removing 
xhci;
GENERIC compiled OK.

xhci could be included in GENERIC with # at the beginning of the line and a 
note 
#experimental: may be broken, use at your own risk

That way, users would know it's a work in progress as opposed to being ignored.
