PROBLEM: black pixels on X with kernel > 2.4.1

[Kilobug <kilobug@freesurf.fr>]

  Hello,
   I don't know if it's an X or a linux problem,I'm really sorry if I 
bother you for nothing.

Here is the bug report:
1. black pixels on X with kernel > 2.4.1
2. when I use any kernel > 2.4.1 (I've tried with 2.4.2 and 2.4.4) some 
areas and some pixel on the X server becomes black (or really darker). I 
have a Riva 128 grapical card, with XFree4 and the "nv" driver.This 
appears both with the Framebuffer enabled and disabled
3. graphic X
4. 2.4.2, 2.4.4
5.  None
6. None
7.1 Here is the ver_linux with the 2.4.1 kernel:
