OK, it sounds like your C64 is defective to me.  There must be some issue with
the PLA or the IO port ($00/$01) on the 6510 so it crashes when it changes
memory configurations.  Someone else had this problem recently where their C64
would run some programs, but anything that changed the RAM config port would
crash.  Unfortunately, you'll need another C64 to troubleshoot that completely. 

As for the 64-cycle VIC, you don't have one, but there are plenty out there and
they really aren't that incompatible.  There may be a few games that get their
graphics skewed, but it's a very small minority.  All 6567R56A are like this and
they aren't rare- there are hundreds of thousands of them out there.  :)
