To be honest, I looked at the FreeBSD agpgart driver a while after I
had split out the Linux one into seperate subdrivers, and thought
"Shit, they got it right first time, why didn't we?"
It's a *lot* cleaner than the Linux one used to be, and in some parts,
still is.

In an ideal world, we would have had a common codebase with wrappers
for Linux/BSD functionality. The DRI folks seem to have got that bit
right at least. Had this happened, FreeBSD would now have AGP3 support
too 8-)
