Sounds like the usual endianness problems ... What depth?
Right the accelerated functions aren't big endian friendly, it also needs to switch the framebuffer to the right byteswapping for the depth in big endian machines.

So i was just wondering if anyone had any ideas on getting it to work or am i wasting my time.....AFAIK Kostas has the 3Dfx fbdev working.
I am attaching the patch that i use (which is far from perfect at the moment) i did so i could work in fbdev support in the xfree tdfx driver. Text accel is disabled, i also use a 32mb mapping for the registers to include the 3D registers (needed by the xserver). The xserver also needs a fb mapping with twice the ram size (for tiled memory accesses also needed by the Xserver) unfortunately this has the side affect that the reported memory from tdfxfb is twice the normal size.
