The method is hardware-dependent.  On some cards, making the cursor line-start
value larger than the line-end value will make it disappear.  On other cards,
making the line-start value equal to 32 (hex $20) will turn off the cursor 
regardless of the line-end value.  Therefore, setting the cursor line-start
value to 32 and the line-end value to 0 should cover both bases.

I've never seen this method fail to work, but then there's a lot I don't see.
If you try this and it doesn't work, I'd be interested to know who makes your
VGA card.
