Hi All, Mark,

Mark, this fixes the abituguru3 driver not detecting the uguru3 on some 
motherboards without the force=1 parameter, see:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=220160

Can you apply this to your testing tree please? Thanks!

Regards,

Hans

This patch changes the driver to also detect uguru3's which hold 0x08 at DATA
initially, as has been reported here:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=220160

Also when an uguru3's holds 0x0014 in the ID register it will now report 
"Abit AB9 Pro" as motherboard identification.
