Same here, I have a dell D610 with the 915M graphics from Intel. Using Breezy I used the vesa driver, and xorg was always between 400 and 700 Mb large in memory. Upgrading to Dapper caused it to use 1.8 Gb, which makes the machine totally unuseable. It is using the i810 driver now, and I am running KDE. -- Borniet
