[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.
