Comment 23 for bug 130979

For what it's worth, I just uninstalled the vbetool package. It also asked to uninstall the related package acpi-support. I let it. I've had no problem since. Suspend works perfectly, no acpi problems (frequency scaling, etc). Don't know why this package is enabled by default, but I kissed it good-bye. Ubuntu 9.04, 32-bit on a Toshiba Portege 3505.
