I already tried. My usual behaviour in case of problems is to disable
everything like acceleration and so :) But the 24bit card absolutely doesn't
work clean. It uses the IBM DAC. The Bt485-equipped 8bit variants work fine.

Hm. My test was scrolling text in an xterm, and i think this should use rect
copying. And is was definitely slower than XFree86 on an 8bit tga. Even
without disabling acceleration explicitly. But have to check this in detail.
But for all this work i have to wait for NetBSD 2.0-RELEASE build complete on
the other Miata. Or for the day when the release is officially downloadable :)

Ah okay. Will hunt for this. I personally don't like Xinerama, i tend to use
multiple Displays. Can't move windows around this way, but nothing hangs
"between" displays or resizes over all 3 TFTs.
