Well, I'm starting my journey into understanding kernel code again. LinuxPMI is really really interesting and cool. Having a lot of fun in fixing bugs, making up patches for them. Its my hope to get the x86_64 port of linuxpmi up to the same functionality as the i386 port, so that when we start fixing/improving it, it will be easier to keep them in sync. Only right now, after my few measely patches the kernel compiles fine for x86_64... Up until linking when it fails with a dozen assembler errors.
