Recently I often get such reports for CL 5428-based cards under svgalib.
Unfortunately Harm Haanemayer, original maintainer and programmer of its
CL driver (and quite some Xfree CL stuff as well) left the net.
I must claim that there is either a bug in the 5428 driver (but it
appeared to work before and noone changed it) or that there are some recent
cards out which are not compatible to the old drivers. In either case, I
think someone with a 5428 and willing to spend some time on it is required
to fix it.
P.S. I don't think this belongs to linux-kernel. Should better go to
linux-x11, linux-svgalib and/or the Xfree maintainers which usually don't
read the linux lists.
