OpenSUSE 11.1 X86_64. Samsung R510 NP-R510-XA05ES. 4 GB ram

This bug is still here. It hit me this week when I bought a Samsung R510
laptop. First solution I found was deactivate ACPI at boot , but this give me a
lot of problems and hard resets when I tried to change display the display
bright, clock delays and many other horror histories. Fortunalely I found the
mem=4GB workaround and at least it is stable and fast. Just I lost 1 GB.

Kerneltrap lists, ubuntu and some other lists also have reports about this bug
and the only fix is, at the moment, the mem=4GB trick.

Some users have reported to fix this problem after a BIOS update, but I'm not
in the list because Samsung still have the 07IL BIOS version for my laptop.

After reading here and there, it seems it is because a bug in BIOS that the
kernel is not able to resolve.
