login fails to bring up unity 3D (2D OK)

[Jim Leinweber]

Had a working install of ubuntu 12.04 precise pangolin beta 1 + patches on an Acer aspire one 722 netbook (amd64, integrated readeon graphics).
Ran update-manager & did partial upgrade on Saturday 2012-03-24, including kernel 3.2.0-20.
Afterwards, GUI login fails to bring up the unity interface. The cursor works, vty switching works, and unity 2D logins work. Kernel version doesn't matter; the results are the same with 3.2.0-17 and 3.2.0-20.
/var/log.Xorg.0.log contains new error messages such as:
  "[ 183.028] (EE) RADEON(0): [DRI2] DRI2SwapInterval: bad drawable"

Not sure if this is a unity bug or a compiz bug.
