The precondition obviously is that the kernel driver has the same HP 2D/3D features as a userland driver. I find it interesting, but doubt that it will work in practice. It's hard to write and maintain a portable graphics driver that works with dozens of OSes. Especially since performance and portability are opposite forces. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
