[HELP NEEDED] Problems with getting the ProSavage PM133 working on BeOS

The computer I am trying to get this running on is a Toshiba Equium 3300M.
It has a Pentium III with 376MB of RAM.The ProSavage PM133 GPU is integrated
and the system has no other graphics card. The GPU works fine under Win98SE
(with drivers) and under Haiku.

I have tried getting the drivers working on BeOS Pro 5. It installed fine
(although in black and white, 640x480, since it didnt have any drivers) but
when I installed the drivers, it would just hang on console message
"sysinit2: 23". It would boot fine if I told it to use the fallback video
drivers in the boot loader.

I also tried BeOS 5 PE Max, which has the drivers for this GPU included, but
that wouldnt even get to the installed, hanging on the same console message.
Telling it to boot with the fall back video drivers got it to the installer.

I have also tried 2 different monitors, but it hung at the same place.

Is there any known fix?
