The KGI ViRGE chipset driver is currently in active development
and does not have these problems. It is a full-featured driver, with
support for MMIO relocation, accelerations (not many yet but the framework
is present and works), and true VGA and S3 'fasttext' textmode support.
It should also be fairly easy to port to other architectures due to the
KGI abstract device I/O scheme used. The developers and testers are
reporting that most modes work, modesetting works, XF68_fbdev works and of
course so does LibGGI and all its apps. And the driver can be used as a
normal fbdev loadable module driver through KGIcon. Check it out.
