S3 SuperSavage IX/C
Linux X.Org driver
This chip is supported by the 'savage' driver as part of the X.Org distribution
Direct Rendering (a.k.a accelerated OpenGL)
Works without any external drivers with Xorg7. After hibernate (suspend to disk) DRI will not work correctly. glxgears runs fine but playing games will hardlock. Workaround to prevent this is rebooting X. After suspend to RAM it works somehow but rebooting X is recommended.
Note: I upgraded BIOS to latest version (1.18) but still no luck. OpenGL (DRI?) hardlocks after hibernate.
Kernel modules: drm, savage
xorg.conf: load glx and dri modules
glxgears gives around ~500 fps.
Display on the internal LCD works as long as you set the monitor settings correct.
External VGA port
Works without trouble, even as Dualhead with xinerama. For swtching on/off use s3switch (also works for TVout).
Linux kernel Framebuffer driver
This chip will work with either the 'vesa' or 'savagefb' driver as part of any recent 2.4 or 2.6 kernel.
Suspend-to-RAM however does not work properly if the framebuffer is enabled. Suspending with X running is fine, so long as the framebuffer is disabled and X is using its own savage driver. With vesafb the screen is frozen on resume (but the system is still running fine behind it). With savagefb it won't even try to wake up. vesafb-tng allows the use of a modular framebuffer, which might fix this- if you can find a way of removing the framebuffer module once inserted.
With kernel 188.8.131.52 savagefb works fine after resuming from suspend or hibernate. You might need to change your virtual terminal once to get it back to life.
