I think I have the same issue, although with a couple of variations (Sony Vaio FW290J):
After resume, my brightness controls do NOT work, although I just discovered that modifying /proc/acpi/video/VGA/LCD/brightness directly DOES work. Also, I have a panel notification icon about a "serious kernel problem" each time I resume. I'm running Lucid Beta.
