One workaround to get Qt 5 working with SGX is simply forcing just the pvr to be loaded by Xorg, creating a specific config:
root@ubuntu-desktop:~# cat /usr/share/X11/xorg.conf.d/99-pvr.conf
# X.Org X server configuration file

Section "Device"
	Identifier	"Video Device"
	Driver     	"pvr"
	Option		"FlipChain"	"true"
	Option		"NoAccel"	"false"
EndSection

Section "Monitor"
	Identifier	"Main Screen"
EndSection

Section "Screen"
	Identifier	"Screen"
	Monitor		"Main Screen"
	Device		"Video Device"
EndSection

Section "ServerLayout"
	Identifier	"Server Layout"
	Screen		"Screen"
EndSection

Title:
  QT5 based applications fails with a segmentation fault with Pandaboard
  and the SGX driver

Status in Ubuntu OMAP4 graphics addons:
  New
Status in “pvr-omap4” package in Ubuntu:
  Confirmed

Bug description:
  While testing Qt 5 support on Ubuntu, and validating the support for
  OpenGL ES2.0 with Pandaboard, I couldn't start Snowshoe (Qt 5 - webkit
  based browser) as it gives a segmentation fault and also breaks the
  X11 server (with the pvr driver).

  After a quick check with Snowball (Mali 400), it worked properly and
  as expected, so this could probably be related with the current SGX
  driver available for Pandaboard.

  How to reproduce the issue:
  1) Enable https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-daily
  2) Install 'snowshoe-mobile' package
  3) Run snowshoe: $ PATH=/opt/qt5/bin:$PATH; snowshoe

  This is with Ubuntu 12.04 with pvr-omap4 1.7.10.0.1.21-0ubuntu1 (from
  archive) and also 1.7.15.0.1.57-1 from TI's PPA.
