I am facing the following problem:
    on a X9SCM with an E3-1220Lv2 I am trying to passthrough the onboard usb 
controllers. I disable the usb module from the kernel config and using pptdev 
the controllers are assigned to ppt devices. However running bhyve on FreeBSD 
10.2 with:

    sudo bhyve -AI -H -P -s 0:0,hostbridge -s 1:0,lpc -s 2:0,virtio-net,tap0 -s 
3:0,virtio-blk,./linux.img -s 4:0,passthru,0/29/0 -l com1,stdio -c 2 -m 2048M 

returns :

    passthru device 0/29/0 BAR 0: base 0xdf823000 or size 0x400 not page aligned

The problem probably that the length of the bar is smaller and not aligned with 
the pagesize. Could the length of the BAR be modified in order to perform the 
pci passthrough?
