That's bad then, because ACPI video support does not work here. I can
boot, and even Fn-home/end works, but it breaks with X.

In old versions, it resulted on black screen after LID close in X.

In 2.6.27-rc5, screen goes black as soon as X are started.

(In old versions, I could use ibm-acpi, and fn-home/end worked even
without CONFIG_ACPI_VIDEO...)
