How to get Hibernation working on a Thinkpad T42

To avoid too much repetition, the basics are laid out here:

To make this work with Mageia, you also have to change some kernel settings:

- disable APIC

- disable ACPI

- edit /boot/menu/grub/menu.lst and add "nomodeset" and "apm=on" somewhere in the line describing your boot options. I put "nomodeset" before "noapic" and "apm=on" after "acpi=off"

- reboot. Make sure apmd is running. If it is, you're set; the Thinkpad keys for sleep, blank screen, and hibernate should all work now. Incidentally, this also fixes a problem where I was experiencing trippy rainbow screen corruption just before shutdown.

second note: after disabling compositing via XFdrake, I stopped experiencing minor screen corruption from KDE menus and stuff like that, and noticed a very small performance improvement. This is for a thinkpad, with a very old, very low-end video card; most of you probably don't need to do this.
