Ralph, Have you tried the 'hdparm -m16 -c1 -u1 /dev/hda' trick? I don't know what it does but it works for me on my Mitsubsi Amity. Several knowledgeable people commented about it on this list some time ago but I don't know what those parameters do nor which actually make suspend work. I did try the command on a desktop machine and started getting hardware problems with the drive so be very cautious.

I expect some messy APM BIOS hook into m$-win, for which I have (yet) not found any documentation/specification. Moreover, I have been asking some IBM people who told be that the hibernation file must be located on a DOS partition, and that it cannot be recognized (I am not sure of it, the explanation was very inaccurate) when not running DOS. Although this last fact is quite IBM-specific (for Toshiba's I have only seen dedicated partitions on the disk for the hibernation space), I suspect that the APM BIOS is quite stuck when the Linux kernel is loaded and running. For short, the built-in "hibernation mode" in our laptops is, in many cases, quite unuseable with Linux. (Any success with other models/brands would be appreciated, I'd really like to know if there are any) However, Tobias Bachmor <[EMAIL PROTECTED]> reported the existence of a "hibernation feature" for the kernel. I am using this feature daily, and it works quite well. Explanations on it follow. For any people that actually rely on the use of an "hibernation mode", this kernel feature does a good job and can, in most cases, replace nearly completely the built-in feature of the laptop. See also below for the present bugs and caveats. Raph
