The patch (version 0.2)
This patch adds a specialised driver for the TOS1900 device adding additional functionality. This driver needs testing on other Toshiba platforms and does not cover all the functionality of the TOS1900 device, just a few nice features (i.e. the ones I could determine the function of from the DSDT table).
The pseudo kbd_backlight device is compatible with UPower, this fixes a problem in the Toshiba ACPI Extras driver where the kbd_backlight Fn key event was handled but no action was taken since UPower could not find a kbd_backlight device.
A word of warning for testers, just because an option is available in the BIOS (and now in the toshiba_tos1900 platform device) does not mean that it will work with your operating system and setup. Specifically, I am talking about the boot_speed option.
