spca5xx-LE is provide as patch to the main kernel for convenience
to set up the patch you need the compressed patch:
usb-2.4.31LE06.patch.gz is the kernel patch to apply at the 2.4.31 kernel
or linux-2.4.31LE08.patch.tar.gz full kernel patch with support of the Usb Wifi ZD1211 and RT2570


patch -p1 < usb-2.4.31LE06.patch in the usb subdirectory of the kernel
or
patch -p1 < linux-2.4.31LE08.patch for the full kernel
your kernel have now support for the spca5xx-LE webcams as the other (ov511 pwc ....)
and maybe some Usb Wifi adaptator like the Linksys WUSB54GV4 or the D-LINK DWL-122 B1 or the Sitecom WL-113 :)
you need to configure the kernel with
make menuconfig
and update the fields if needed:
CONFIG_MODULES=y
CONFIG_VIDEO_DEV=m
CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_SPCA5XX=m
save exit
then compile
make
make modules
