I have only a AGP 2 (geforce 4-mx) card, so I missed that(and with one I would only to be able to say 'it doesn't work' so thanks for your explanation). But without this changes I won't even able to use dga, because the first dga-enabled app completely locks up my box. And to have working AGP2 and non working APG3 looks a lot better for me than no AGP-support at all.
2.5.* is able to 'mostly' boot on my mobo so I can't say anything about that..
