s3fb: fix Virge/GX2
Fix Virge/GX2 support in s3fb: - fix IDs: 86C357 is GX2, 86C359 is GX2+, 86C356 probably does not exist - add memory size detection - drive it the same way as Trio3D/2X The original IDs most likely came from S3 website which claims that: - 356 is Virge/GX2 with ID=8A10, driver included in Windows 2K, XP - 357 is Virge/GX2+ with ID=8A11, driver included in Windows ME - 359 is Virge/GX2+ with ID=8A12, driver included in Windows ME but: - google search for 86C356 only reveals references to Trio3D (probably because of a typo - Trio3D is 86C365) - my card is clearly marked as 86C357, Virge/GX2 and has ID=8A10 - there is no driver for IDs 8A11 and 8A12 in Windows ME - there is a driver for ID 8A10 in Windows ME that says it's GX2 (357) Tested with #9 Reality 334 (86C357 Virge/GX2, ID=0x8A10).
