Including Tony's corresponding "modehelper" kernel-c= onfig patch and -- since 2.6.11-rc5-mm1 -- with an additional patch from Andrew that fixes some compiler warnings (missing type casts). The driver is still not complete (no hardware cursor, ...) but it does its job pretty good (at least on my machine). Only a few changes are required to add support for i915 and they can all easily be derived from the xorg/xfree-driver that already (fully) supports the chipset. Obviously there is someone at xfree/xorg that is either a "hell of a hack= er" or in the position to access the required documentation from intel. Or both. :-) Axel ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
