It sped the framebuffer code up by a factor of 10, but it no longer works. I enabled caching and write buffering to get the speed up, but now only 1 out of every four 32bit words makes it to the screen when a cache line dumps. I'm trying to use a DMA channel to continuously move a RAM framebuffer device into the video chip. Not my first choice, but if it works it will be a significant speed up.

No progress getting any docs from the vendor. They still have not returned any of my calls or e-mails. I've resorted to contacting people I know who have used the vendor's products and trying to get an introduction to the vendor.
