Update: moved code to

Friday evening I sat down and wrote my first piece of solaris kernel code and an associated user-space application that activates the brightness up/down hotkeys for the LCD on my Toshiba Satellite M30.

I implemented a tosh_hci driver that can perform Toshiba Hardware Configuration Interface traps via an ioctl(2). This driver is really simple; the hardest part being the intel assembly needed to perform the trap (technically an inb instruction, not a trap).

The userspace code is a really slimmed down version of the code that I previously made available in my patch to the linux acpid. It currently only handles the LCD brightness keys because none of the features that the other hotkeys are supposed to invoke are currently supported by solaris/opensolaris.

Anyhoo, I've made the source available, under the CDDL, in a bundle here for any other toshibans that might like to get a bit more comfort factor back when running solaris.
