I'll take your word for it. :)
Today I discovered that --disable-dri in the driver is a no-op because
xorg-server.h defines XF86DRI* anyway. So I'm thinking maybe the drivers
shouldn't bother with defining them but just require the other
prerequisites when xorg-server.h defines them. Or is there a scenario
where --disable-dri is required even though the server was built with
DRI support? (I'm finding it quicker to #undef XF86DRI in config.h for
