Hi
Is there going to be support for the nForce2 AGP in 2.4.22? AFAIK it's already
in 2.5, but the nvidia-patch only works with 2.4.20, not with 2.4.21. Are there any plans to backport AGP-support from 2.5 or modify the nvidia-patch to work with 2.4.21/2.4.22?
Please CC me.
Thanks.

Hi,

This is the original nvidia agpgart patch from 261 drivers with the modifications needed to work with 2.4.21+ kernels. If you have any doubts, go to the forum on nforcershq.com. Good luck.

By the way, I hope to see it in 2.4.22 too. A lot of people in nforcershq.com have been using this patch or 2.4.21-ac* without any problems.
