34ed25f50b s3fb: updates
Move s3fb_get_tilemax to svgalib.c as svga_get_tilemax, because it reports
limitation of other code from svgalib (svga_settile, svga_tilecopy, ...)

Limit font width to 8 pixels in 4 bpp mode.

56c7554938 s3fb: implement fb_get_caps
Implement fb_get_caps().  This will allow the driver to tell upper layer that
it can only support 256 8x16 bitmaps when in tileblitting mode
(var->bits_per_pixel == 0);

8db51668f5 s3fb: limit 8x16 rectangles when tileblitting is enabled
If tileblitting is enabled (text mode), the hardware can only accept 8x16
bitmaps. Advertise this to the upper layer. And to ensure that an appropriate
font is always available, select an 8x16 font in Kconfig.

a268422de8 [PATCH] fbdev driver for S3 Trio/Virge
Add a driver for S3 Trio / S3 Virge.  Driver is tested with most versions
of S3 Trio and with S3 Virge/DX, on i386.

(akpm: We kind-of have support for this hardware already, but...

virgefb.c
  - amiga/zorro specific,
  - broken (according to Kconfig),
  - uses obsolete/nonexistent interface (struct display_switch)
  - recent Adrian Bunk's patch removes this driver

S3triofb.c
  - ppc/openfirmware specific
  - minimal functionality
  - broken (according to Kconfig),
  - uses obsolete/nonexistent interface (struct display_switch)
)
