Thanks, I remember this being discussed several times in the distant past, but it's been a while. The upshot is that, on OS/2, you should start the X server while the OS/2 desktop is in a VGA mode. Apparently, OS/2 provides an automatable way of doing that, but I don't know what that would be. If you start the server from a non-VGA mode, the XFree86 driver is required to restore the timings it sees on entry, but not video memory contents. Your report would imply that's not happening correctly in the radeon driver.
