2 bugs in the X server

Hello,
  I know about 2 bugs in X server which are quite reproducible with my programs.
I use CVS from a month ago, but I noticed the first bug months ago already.

I use mga driver.


1/ There is a way to see a screen full of pixmaps (instead of what should be on
   the screen).

  I can reproduce this bug with sawfish WM.
  It has a mode to flip between viewspaces, while moving a window by mouse
  movement (and bumping into the border of the screen).

  When I do such movement w/ keyboard using mouse emulation, I can trigger this funny
  bug. Suddenly, after Sawfish does a series of requests to move windows, and
  warp pointer, I see pictures which are used in my (running) firefox browser,
  and I explain this that I see "off-screen" pixmaps.

  To recover from the wrong display I can either switch to another  console, or
  cycle resolution with  C-M-KP+/-.




2/
  DBE (double-buffer extension) operations can make the server segfault.

  My guess is, that it is caused by the double-buffered window being too large:
  the DBE request are made by my quick & dirty experimental code for Sawfish, to
  draw window's title-bar, and the bug happens, when I construct a too large
  window (building gtk view-text widget with a long line inside, w/o scrolling
  enabled).

  Here's the ....

And I would like to ask, if there's a hope to get support for RV370[Radeon
X300SE] in xfree86.

Thanks!
