toshiba_acpi no control of display backlight after suspend to ram
toshiba portege r705
After boot, display backlight control works fine.

After suspend to ram, wake, suspend to disk, wake backlight control returns to working state.
When control is not working, on screen display does work -- indicating backlight changing brightness (even though its not)
Additionally, the max_brightness=7 and the count starts at 0, but there are only 5 levels when adjusting using control buttons. And even more oddly, when increasing from 0, display_brightness goes like this:
And when decreasing from 7, it goes like this:
Although i think this needs to be filed against a different component, (suggestions?) i thought it might be valid here as well.
