But it does export some function to be called from user space. Another kernel module can of course utilize these functions as well. At least if you know on how to use them. :) >Hope this clears up any misconceptions for sure this time. ;o) Yes. :) >The most useful stuff for you is most likely the 2D XFree86 "nv" >driver source code, and whatever might be in the Linux kernel >framebuffer driver, or BSD et al.

Wish you the best of luck nonetheless. I give it a try at least. :) -- Gerhard Gruber Für jedes menschliche Problem gibt es immer eine einfache Lösung: Klar, einleuchtend und falsch.
