s3fb: Add Virge/MX (86C260)
Browse files Browse the repository at this point in the history 
Add support for Virge/MX (86C260) chip. Although this is a laptop chip,
there's an AGP card with this chip too.

Tested with AGP card, will probably not work correctly with laptops.
DDC does not work on this card (even in DOS or Windows).
