System: NetBSD 5.99.23 (GENERIC) #0: Mon Jan 11 17:47:30 UTC 2010 builds@b8.netbsd.org:/home/builds/ab/HEAD/i386/201001110000Z-obj/home/builds/ab/HEAD/src/sys/arch/i386/compile/GENERIC

>Description:
USB Device Controller (UDC) and USB Options Controller (UOC) support in
the AMD CS5536 Geode LX chipset is missing in NetBSD:

vendor 0x1022 product 0x2096 (USB serial bus, interface 0xfe, revision 0x02) at pci0 dev 15 function 6 not configured
vendor 0x1022 product 0x2097 (USB serial bus, interface 0x80, revision 0x02) at pci0 dev 15 function 7 not configured

The UOC is used to switch USB port(s) between host and device modes.  In
device mode, the port is controlled by the UDC.
>How-To-Repeat:
boot kernel.  note missing driver support.
>Fix:
add driver support.  Linux drivers are available from AMD at
http://www.amd.com/files/connectivitysolutions/geode/geode_lx/08_-_Patches_Linux2.6.11_Common_02.03.0100.patch
documentation on AMD CS5536 chipset is available at
