I found a workaround: Just suspending and resuming, with KMS enabled. Tested with Lucid and Karmic.

After suspending and resuming, it starts showing the same notification as when running Windows (so... BIOS-related?): a blue rectangle in the upper left corner showing 'bars' (like a wireless signal) representing the current brightness level.

(The bug happens in the Fedora 12 LiveCD too, in the few seconds before it threw a "No root device found" error that stopped it from booting.)
