I'd like to point out that the linux-image-2.6.36-0-generic that popped up into Natty suddenly resolves this issue.
Meanwhile, the 2.6.35-22.34 that is currently pulled by linux-generic does not.
This seems to indicate that this has indeed been a kernel issue all along and NOT a BIOS issue!
It would be highly desirable to for the kernel team to find out exactly what fixed it and to backport the patch into Lucid.
