Yeah I found this afternoon when I turned the console framebuffer off
this helped X.  Though I don't use the console often, I might try
vesafb.

Thanks for that, looks useful!

He doesn't seem to have a solution for if I leave the mouse plugged in

Yes, thanks.  I will give the DRI driver from dri.sf.net a try.
