ok my observations:
- it builds without patching with the 2.6.24-rc3 kernel
- the control center works now
- some apps still hang (including the control center) when they are the first program that talks to the driver
- compiz still doesn't work with xserver 1.4 (but I don't need that)
Overall I'm happy with this release. It installed flawlessly even on the latest kernel, that hang thing doesn't bug me that much and I can live without compiz.
