I'm using kernel 2.6.9, with Debian-specific patches (does not include ACPI-related stuff, as far as I can tell). I'm trying to get suspend-to-ram working on the machine, but when it resumes, the trackpoint (a PS/2 device) doesn't work. I have confirmed that the issue is at the kernel level and not the X level by cat-ing /dev/input/mice and observing that nothing comes out when pushing on the stick. Removing the psmouse module before shutdown, and inserting it after restoration does not work around the problem. The issue appears to be similar to what was discussed in the thread "Re: trackpoint dead after S3 suspend" in late November, 2003 on this mailing list [1]. The last post in that thread said (with regard to a patch reported to at least partially fix the problem), "See l-k to find similar code done less ugly way... (I did it yesterday)." Does anyone know which patch the poster was referencing? Alternatively, what other techniques could work around the problem?
