Intel doesn't make the drivers for Apple, just Windows and Linux. And *BSD is no business at all and it the end it's just business that counts for a company. Apart from that, enjoy AMD as long as possible, because if there is no GEM/KMS in the near future, your ATI-driver will be doomed too.
It is especially vital for Linux drm GEM, TTM, KMS code to be ported immediately to the BSDs because developers are in the process of removing userland modesetting code from current graphics drivers. To paraphrase what we have been told by freedesktop.org developers, if we do not port this code, very shortly the BSDs will be left only using the simplest VESA driver at 1024 x 768 resolution with no hardware acceleration.
Finally it's not the problem of Intel, or some Linux-guys, it's the sole problem of the FreeBSD-community. If there is no support (maybe there is just no one able to do it), then there won't be a FreeBSD-desktop anymore. And without a desktop, FreeBSD's decline is mandatory. FreeBSD as server-OS doesn't need the desktop, but it needs the advocates of the desktop-crowd :-)
