[coreboot] Epia-CN USB Does Not init Properly with LAB

The epia-cn works fine with FILO, except for the lack of VGA console. X 
however works fine. When you drop out of X the screen is left with 
vertical bars until X restarts. The PS2 keyboard is still responsive 
when out of X.

The epia-cn does not init the usb controler properly with LAB. Does 
anyone have any idea what the kernel in LAB may be getting wrong?

Serial debug output with LAB:

The kernel is built with buildrom along with kexec and the initrd.
Linux version 2.6.22.2BuildROML-A-BV1.0

Coreboot is used to build coreboot and the config.lb uses the elf.lzma 
from buildrom as a payload.
