I’m running a ppc64 kernel with ppc32. This combination has a few shortcomings. One was that the kernel’s evdev driver had no 32-bit compatibility. I couldn’t use XFree86’s evdev support because of this, and hal had some problems too. I finally was annoyed enough to hack the evdev driver. Here’s the ugly patch:
evdev-compat-2.6.11-rc3-mm2.patch

March 16th, 2005: The patch has been integrated into 2.6.11-mm3
