[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.

+          Say Y here if you want a VGA text console via the USB dongle or
+          want to support userland applications that utilize the driver's
+          display mode switching capabilities.
+
+          Note that this console supports VGA/EGA text mode only.
+
+          By default, the console part of the driver will not kick in when
+          the driver is initialized. If you want the driver to take over
+          one or more of the consoles, you need to specify the number of
+          the first and last consoles (starting at 1) as driver parameters.
+
+          For example, if the driver is compiled as a module:
+
+             modprobe sisusbvga first=1 last=5
+
+          If you use hotplug, add this to your modutils config files with
+          the "options" keyword, such as eg.
+
+             options sisusbvga first=1 last=5
+
+          If the driver is compiled into the kernel image, the parameters
+          must be given in the kernel command like, such as
+
+             sisusbvga.first=1 sisusbvga.last=5
