Your patch seems to be on the right track, and yeah, GL_VENDOR_APPLE is a good
idea since Apple drivers have their unique set of bugs. We'll probably want
GL_VENDOR_APPLE(all OSX drivers), GL_VENDOR_NVIDIA, GL_VENDOR_ATI,
GL_VENDOR_MESA(all mesa). Probably in the future GL_VENDOR_INTEL for the
windows intel driver, but that's not something that should be in this patch.

I am afraid we'll need a card detection routine for each GL driver vendor and
hardware vendor. At least the fglrx card detection can't be shared with Mesa's
since mesa just tells you the chip name like RV580 while fglrx tells you the
marketed name(like Radeon X1600). Some may be reusable though since OSX and the
linux binary drivers seem to have some common GL strings.

You could set up a control table:

{
    {GL_VENDOR_NVIDIA,    HARDWARE_VENDOR_NVIDIA,    
match_nvidia_card_binary},
    {GL_VENDOR_APPLE,    HARDWARE_VENDOR_NVIDIA,     match_nvidia_card_binary},
    {GL_VENDOR_MESA,    HARDWARE_VENDOR_NVIDIA,     match_nvidia_card_mesa},
    {GL_VENDOR_MESA,    HARDWARE_VENDOR_ATI,        match_ati_card_mesa},
    etc
}

and then search for a matching gl and hardware vendor combination and call the
function. If none is found write a FIXME and guess a generic dx7 / dx8 / dx9
card depending on the hardware vendor and GL capabilities.
