Hi, so that's the change in libdrm, but when in xf86-video-intel did the code
start to use the new libdrm abi?

And is there a patch I can apply to the older versions of xf86-video-intel (not
to libdrm) to allow them to work with the new libdrm? I'd rather just bisect
xf86-video-intel's code and reinstall that package than downgrade libdrm on mys
system (that sounds a lot more dangerous).
