john, "S",

this is an ATI radeon R300 chipset (we have one card of that type
here in the CMM, IIRC). there is a wiki describing ATI card support
under linux at:
http://wiki.cchtml.com/index.php/Open_source_drivers
since AMD is now making documentation available, the open source
drivers should have improved significantly since 2006...

there also should be a "legacy" version of the proprietary
fglrx driver for this chipset from AMD at:
http://support.amd.com/us/gpudownload/Pages/index.aspx

since the fglrx drivers have always been a bit ticklish
it may still be required to disable advanced OpenGL via
setting VMDSIMPLEGRAPHICS to 1.
