What I am using:
- ti-ezsdk_dm816x-evm_5_03_01_15 and freshly installed filesystem on a SD card
- Qt 4.7.4 built as per http://processors.wiki.ti.com/index.php/Building_Qt_with_OpenGL_ES_accelerated_by_SGX
- Installed Qt 4.7.4 lib and plugins to /opt/qt-embedded/ on SD

Linux Kernel version
Linux dm816x-evm 2.6.37 #1 Wed Aug 1 16:37:15 EDT 2012 armv7l unknown
My Qt 4.7.4 configuration (from config.status):
configure -confirm-license -prefix /usr/local/Trolltech/QtEmbedded-4.7.4-arm -opensource -embedded arm -platform qws/linux-x86-g++ -xplatform qws/linux-TIarmv7-sgx-g++ -depths 16,24,32 -no-mmx -no-3dnow -no-sse -no-sse2 -no-glib -no-cups -no-largefile -no-accessibility -no-openssl -no-gtkstyle -qt-mouse-pc -qt-mouse-linuxtp -qt-mouse-linuxinput -plugin-mouse-linuxtp -plugin-mouse-pc -fast -opengl es2 -qt-gfx-transformed -qt-gfx-vnc -qt-gfx-linuxfb -qt-gfx-multiscreen -plugin-gfx-powervr -D QT_NO_QWS_CURSOR -D QT_QWS_CLIENTBLIT
My current environment:
root@dm816x-evm:~# export
export EDITOR='/bin/vi'
export HOME='/home/root'
export LD_LIBRARY_PATH='/lib:/usr/lib:/usr/local/lib:/opt/qt-embedded/lib'

So, I am able to build the hellogl_es2 against my newly compiled Qt 4.7.4 toolchain and when I run it on the EVM, it shows the exact same thing as the default 4.7.2 version does on the screen and shows this on the command line:
root@dm816x-evm:~# ./hellogl_es2 -qws
Found SGX/MBX driver, enabling FullClearOnEveryFrame
Found v1.4 driver, enabling brokenTexSubImage
Found non-Nokia v1.4 driver, enabling brokenFBOReadBack
Unlike the 4.7.2 version, I can't see the mouse pointer move when I try to use the mouse. When I run the 4.7.2 version in the /usr/bin/qtopia/examples/opengl/hellogl_es2 directory, I see the same thing on the screen, I can use my mouse and I get no verbose messages on the command line.
I was comparing the Qt mousedriver directories between the default and what I have:
root@dm816x-evm:/usr/bin/qtopia/examples/opengl/hellogl_es2# ls /opt/qt-embedded/plugins/mousedrivers/
libqlinuxtpmousedriver.so libqpcmousedriver.so
root@dm816x-evm:/usr/bin/qtopia/examples/opengl/hellogl_es2# ls /usr/lib/qtopia/plugins/mousedrivers/
libqtslibmousedriver.so
So, this looks like one of the following possibilities:
- Qt 4.7.4 installation on the target filesystem is missing some Qt and/or other mouse driver
- Qt 4.7.4 configure step didn't include some mysterious (to me) option that is needed
- The tslib and friends is really not optional and I need to build it in order for the mouse stuff to work.
