[coreboot] problem with wake from suspend (asus chromebox 2955u)

[a a]

I have  a chrombox (asus 2995u) that in setup last weekend using coreboot and 
seabios fix to install linux (ubuntu 14.04)  The system runs fine with one flaw   
and I can't find the fix; it only wakes from suspend if I hit the power button - 
usb devices (mouse, keyboard, ...)  does not wake the system.  Given that I 
installed it last weekend (~Aug 9) I thought it carried the wake from usb fix 
that was added in july are there any suggestion for fix or work around ?
