haiku/headers/private/graphics/s3savage/DriverInterface.h
Axel Dörfler b9ecaef57a Added the S3 Savage driver from BeBits - accoring to Siarzhuk it doesn't work yet
under Haiku, though. If someone has access to this card, feel free to fix this :-)
I renamed the driver to s3savage (from BeSavage), and added the license text
separately (dunno if that's really needed, though).
