How to use directfb on Qt ?

Hi Sirs,
Somebody could tell me how a can put Qt to use a directfb driver ? I tried using myprog - display direcfb and a env var QT_DISPLAY so, Qt still not found the driver. Perhaps I didnīt build the driver. Can someone send me a checklist about this config ?
Iīm using buildroot to build this configuration/distribution and a ARM platform (PXA300 with MMX suport). Qt using linuxfb is working well, but I need more performance to my graphics.

Look at dmesg and use apropos or locate to find the driver.
