How to get SGX OpenGL working on BeagleBone

Hello, I'm trying to run the SGX demos included with the TI Sitara SDK
05_03_02_00 from 12/2011. The demos all error with
"PVRShell: Unable to initialise EGL".
PVRShell: EGL Error (EGL_BAD_ALLOC)
I noticed the omaplfb kernel module doesn't load: "omaplfb:
OMAPLFB_Init: OMAPLFBInit failed"
I added some kernel boot arguments for graphics memory allocation as
suggested, but the module still doesn't load.
Please help. Thanks.

Here's the output of gfx_check.sh
WSEGL settings
[default]
WindowSystem=libpvrPVR2D_FRONTWSEGL.so.1
