BTW, if this driver will support only multiples of 8 font widths at less
than 8bpp, you might want to advertise this limitation to the console,
so it won't accidentally load an incompatible font.  The pertinent
fields and function would be info->pixmap.blit_x and fb_get_caps().

An example would be s3fb.  In tileblitting/text mode, it can only handle
certain fonts (specifically 8x16 fonts)

See s3fb.c and svgalib.c in drivers/video.
