I am using linux-2.1.xxx with glibc-2.1 (later time ago 2.0) and precompiled
XFree86-3.3.2-glibc SVGA server running on Tseng ET6100 cards in 32 bit mode.
Later time ago (for 2.1.1xx, I have no backup) I have reported this
bug, which causes horizontal lines on bottom part of screen. I have
obtained small patch from Martin Mares:

This patch (now part of kernel) have solved most of these cases,
but there resist following cases, when bug still occurs:
Pressing Ctrl + Alt + Num+ / Num - (change display mode)
Pressing Ctrl + Alt + Fx (switch to / from linux console)
Looking preciselly on drawing these lines, these lines are drawed
not only during switching, bad also few time (cca .3 sec) after.
