Can we create a hmm... "inverse patch" or sth like that for GTA01 - just for 
testing purposes, to provoke flicker there and make sure it's _absolutely_ 
nothing in hw of GTA02, but really is nothing but a bug in LCM?
Just an idea...
And maybe manufacturer of LCM can tell what's the very nature of this bug, so 
this became more of a real fix for a well understood problem, rather than a 
workaround which seems to help for now but the bug may resurrect when nobody 
expects.

Also, you said the PCLK signal is very corrupted due to the R-C. Even while 
apparently not causing actual trouble, this should be given a closer look, to 
feel good regarding worst case scenarios. Someone has to have an explanation 
_why_ this C is there and should be this value. Otherwise just replace with a 
better value for MP?
