The toshset in the AUR doesn't seem to work for the latest kernel - there's a gcc error.
Can someone please create a working package?
Have you reported it on the relevant page?
If not, why not?
If so, it may help to post a link so anybody interested can take a look easily.
I have reported it on the relevant AUR page: https://aur.archlinux.org/packages/toshset/
According to https://bbs.archlinux.org/viewtopic.php?id=147221 the issue is that it must be updated to support gcc 4.7. I'm not experienced in these things, but I'll try to take a look at it.
For one thing, this package resolves an issue on many toshiba laptops where you cannot change the brightness of the screen once resuming from suspend/standby.
