First would like to say to G.Skill support. Consider this more of an 'fun' than an "RMA the damn thing"-style of stuff (of course nothings fun to you guys just work.. ). Just in case troubleshooting this way would be even an option. I know pretty well how this memory performs and on what conditions, so, just matter of trying something what seems to absolute impossible.
That out of the way, here we go, if someones willing over there, setup specs:
1. take an ASUS X38/X48 board and drop full controller 8GB PI-B chips or even 2 chips will do in it. Something like ASUS Maximus Formula, P5E, Rampage Formula would do nicely. (Plus some core that can handle these speeds with out heating to hundreds.)
2. Now, there's an trick on ASUS boards to get this POST at CL5-5-5-15 simply reset CMOS or use the 'Load BIOS Default' Boot that up and OC the core so 6:5 will become 1067Mhz.
(This will OC the memory voltage also to 2.448v. So that might be too much it'll POST around 2.06-2.10v at BIOS (~2.20v). Also North bridge probably will need 1.55v South Bridge will stabilize itself automatically after reboot.)
3. Now can anyone on support actually get this run stable by any means other than dropping CL6?
If this is actually possible let me know. Although, It's not considered as stable by MemTest86+:
* Any CL5 will do I don't even care, if it's CL5-20-20-20 in that sense.
* Any voltage will do (Range is 1.80-2.60v and on these asus boards all values are +0.10v automatically which doesn't even depend on BIOS).
* Please drop this setup to +2048MB LinPack x64. Screenshot of any would be nice even MemTest86+ Stable Test 5.

System Setup I am using to test this 'theory':
ASUS Rampage Formula
OCZ GameXStream 850W (with multimeter checked decent 12V, 5V, 3.3V on these speeds.)
Intel Q9450 (with decent VID to out perform these FSBs)
F2-6400-CL4D-4GBPI-B (4x2GBGB) / F2-8500CL5D-4GBPI-B (2x2GB)
RAID-0
ATI Rage 3D PCI (My damn GPUs are still on RMA, lol, but this does just fine.)
Windows XP x64
Above descripted Start parameters.
CL: 5
tRCD: 5
tRP: 5
tRAS: 15
tRRD: 5 (gonna dump this straight to somewhat ideal)
tRFC: 70 (gonna dump this straight to somewhat ideal)
tRT: 5 ("Read PRE Time" gonna dump this straight to somewhat ideal)
Rest as 'Auto'. All 3 stages available.
