The kernel driver compilled by me on -cuurent. The OpenGL library by 
nvidia on 4.x for sure.
Can you say is this http://www.minion.de/files/machdep.c.diff supposed

Well just give me a hint which one should be removed:

options         COMPAT_43               #Compatible with BSD 4.3 [KEEP

options         COMPAT_FREEBSD4         #Compatible with FreeBSD4
