If FAT_CURSOR is not defined, pccons.c sets cursor_shape by reading the
cursor start and end raster registers in the 6845.  This won't work if it
really *is* a 6845 since these registers are write-only.  So, on my humble
hercules card, the cursor ends up as an overline -- a little umm

Solution: define FAT_CURSOR for cards that actually use a 6845.  Or add a
CURSOR_SHAPE feeping creature...
