Compiz issues on Intel Integrated Graphics Chips

Question

I've upgraded to 11.10 from 11.04 on a Toshiba Satellite L305-S5907 and can't get Compiz to work anymore. Metacity runs in it's place and "compiz --replace" gives the following errors.

lspci -v gives

I have uninstalled all non-Intel drivers and software packages(ATI, NVidia). Mesa is installed. Using the "compiz-check" script, I get:

Gathering information about your system...
Distribution:          Ubuntu 11.10
Desktop environment:   GNOME
Graphics chip:         Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Driver in use:         Unknown
Rendering method:      None

Checking if it's possible to run Compiz on your system...  [SKIP]

Checking for hardware/setup problems...           [SKIP]

At least one check had to be skipped:
Error: No rendering method in use (AIGLX, Xgl or Nvidia)

I have purged and re-installed compiz with no luck. I have deleted all of the ~/.config/compiz* folders with no result. Nothing OpenGL works (e.g glxgears, games, etc). Tried Compiz Fusion but it doesn't switch over to compiz.

Thanks in advance for the help.

EDIT: I have edited my /etc/default/grub to have the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=" 

Where previously was: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

I have also gone into gconf-editor in Desktop>Gnome>Applications>Window_manager and removed the current and default window manager entries entirely (not just change values).

THEN, compiz --replace works, if I set it to load at boot. What a pain.
