ICR2: UniVBE not compatible with CL 5428?

In the quest for faster frame rate I wanted to try the UniVBE driver that comes with ICR2. When I setup the game to load it, UniVBE loads and recognizes the CL5428 graphics chip and the Papyrus logo appears for a second then the game exits with an error message stating "Unable to load ROL(0). Incomplete install or not enough memory." The Papyrus tech support tell me this indicates that the UniVBE driver is incompatible with the CL 5428 but I find this hard to believe given how popular this chipset is and I have another game (US Navy Fighters) that runs with UniVBE loaded. Any opinions?

I have a CL-542X and it works fine with that on a DX4-100. Doesn't help frame rate on VGA mode, only in SVGA. Jeff.
