Dec AlphaPC 164lx and intergraph realizm z13

Good day everyone!
On my Dec Alphapc 164 lx I installed Intergraph realizm z13, after installation TRU64 Unix 5.1B kernel use standart vga driver, I tryed to install drivers for powerstorm 4D50T package from Associated products disk 2, but after rebuilding kernel and reboot when TRU64 tried start X11 I recive black screen. So thats my questions: can realizm work on Tru64 Unix(by the way, my realizm have DEC label), what kind of driver I should use to run X11 on TRU64?!
