--Boundary_(ID_SSwUc7p4vsN0N10isZrd2w) Content-type: text/plain; charset=UTF-8 Content-transfer-encoding: 8BIT Attached patch is the 7.0-CURRENT (September 23) adaptation of http://marcus.grupos.com.br:8080/patch/agp_i810.c.patch which gives me /dev/agpgart and allows me to use Xv extension on my ThinkPad X60. Still no direct rendering, though.
