Well, I think it *is* controlled in hardware. My point was that cursor's
going to be running his little butt off since we refresh the screen so
much. I'm still going to implement this, because quite honestly it's a
good thing to offer people more choices, even if one of those choices ends
up being "flickering-like-mad but still cool looking hardware cursor".
Who knows? It might not be so irritating after all; we certainly (when
things are configured right, that is :) can't see the LCD refreshing as it
is ... if the hardware cursor is implemented right (i.e. an internal timer
determining whether the blinker is on or off, that can't be manipulated by
software and is guaranteed to be consistent), it should actually kick some

LCDproc does definitely include overhead, but it also takes care of much
of the grunt work in dealing with the LCDs. Look at the parallel stuff, in
particular. I would *not* want to develop that myself, and I am still in
awe of the folks here who pulled that stuff off :)
