Hello Kevin,

I am right now working around enabling the sio controller on the truxton 
(SMSC SCH5027D) so I can try
to install windows in fact, "Press any key to boot from CDROM".

The main board we are designing do not have any superio controllers so 
usb kbd/mouse is something we will need
to implement here. However, I will take the easy way, a SMI handler. I 
am waiting another document from the Intel
dudes providing some guidelines about this specific usb keyboard support 
via SMI. This is going to be very HW
specific unfortunately.

It took 8 weeks to receive the last document we have requested. So I 
guess I will be asked to place the project on
the side until we get the document. We should receive our first hardware 
prototype somewhere late October this

Am going to send patches to the list as soon the superio controller is 
supported as this is going to be end of our first
engineering milestone.

Thank you,
