[PATCH] USB: sisusb[vga] update

here is a new and extended version of the sisusbvga (previously: sisusb)
driver. The patch is against 2.6.13 and updates the driver to version 0.0.8.

Additions include complete VGA/EGA text console support and a build-in
display mode infrastructure for userland applications that don't know
 about the graphics internals.

Fixes include some BE/LE issues and a get/put_dev bug in the previous
version.

Other changes include a change of the module name from "sisusb" to
"sisusbvga". The previous one was too generic IMHO.

Please note that the patch also affects the Makefile in
drivers/video/console as the driver requires the VGA 8x16 font in case
the text console part is selected.

Heavily tested, as usual. Please apply.

One thing though: I already prepared for removal of the "mode" field and
the changed "name" field in the usb_class_driver structure. This will
perhaps need some refinement depending on whether you/Linus merge the
respective core changes before or after 2.6.14.

+
+	  For example, if the driver is compiled as a module:
+
+	     modprobe sisusbvga first=1 last=5
+

+

+
+	  If the driver is compiled into the kernel image, the parameters

+
+	     sisusbvga.first=1 sisusbvga.last=5
