ASUS L3800C, rest pretty much the same.

In my case, acpi_sleep=s3_bios is enough. If that doesn't work, you may try
the new radeonfb driver from 2.6.3 -- on my box it *at least* manages to
get the backlight on without having to pass acpi_sleep, but then it screws
up some other things so the laptop gets locked anyway.
