From my lspci:01:00.0 VGA compatible controller: Trident Microsystems CyberBlade/i1 (rev 6a)
I'm running XFree86 4.3.0 on a RedHat 9 system (Kernel 2.4.24 from kernel.org). Even though it's not a Debian system, the screen-shot looked so familiar. And it's always green. I thought the issue may not be distro-specific.
