If the core doesnt have enough information to do something, it probably doesnt need information about it in the first place, and that information should be kept in the extension module. As far as video memory allocation, there are existing core routines that handle that. Utah-glx now uses the core routines to alloc video memory. ------------------------------------------------------- This SF.net email is sponsored by: The Definitive IT and Networking Event. Be There!
