AMD Sempron(tm) Processor 3000+
Fresh installation on resurrected MSI K8MM-V MS-7142 motherboard.
openSUSE Tumbleweed, kernel 4.10.4, server 1.19.3, ati driver 7.9.0

Mouse cursor is about all that can be counted on. Sometimes an app like Xterm 
can be started, but text is smeared if it appears at all. As likely as not, the 
IceWM desktop mostly paints, and nothing more is possible, sometimes to the 
point even remote login cannot force reboot or kill X. The following is the tail 
of dmesg with drm.drm_debug=1 on cmdline (without it, no clues show up in dmesg 
or Xorg.0.log) using RV250/M9 GL [Mobility FireGL 9000/Radeon 9000 (similar 
results if I swap the RV200 for the RV250)(journal looks about the same):

Is there something, other than the illogical 'agp=off' cmdline option, that can 
be done to make these cards usable? Time to file a new bug? I don't see any that 
match in a Driver / ATI, Drivers/DRI/r200 search.
