How about some clever code to swap unseen screen bitmaps to/from FAST
memory??  I've been toying around with this idea for a few weeks
now.  I haven't really spent the time to work thru the problem completely,
but I can imagine this as a potential solution to the CHIP mem crunch.

You'd have to get down and dirty replacing quite a few graphics/intuition
library functions, and you might even have to write software equivalents
of most of the graphics calls, or else block tasks attempting output.
But it COULD be done (couldn't it??).

Am I completely off-the-wall?
