Support for this chip appears to not have been brought forward into the
XFree86 4.x driver.  XFree86 3.3.6 supports it in case you wanted to try
that.

Something else you can try is to use the 'vesa' driver.  I'm not sure if
your bios has sufficient VBE support to do it, but it's worth a shot.
This will be unaccelerated though it will give you high color modes.

The XFree86 driver doesn't use interrupts, but I find it very strange
that the chip's IRQ is connected to IRQ 0.
