What about the blitter (won't work above 20 MHz) and what about using
experiences from other accelerators, whose also overclocked the bus to
25 MHz, and the results are: unstabilities, damaged blitters, damaged
whole motherboards, generally shortened Falcon's lifetime?

The first 50/25 MHz accelerator (50 MHz CPU, 25 MHz bus) was developed
here years back (about 1994-1995). Looking at what happened later to most
of accelerated Falcons, I am glad I didn't get it. 25 MHz is too high rate
for Falcon custom chips, that's the resulting experience.
