I haven't tried using SetDIBitsToDevice to reduce flicker, but this banding suggestion might work?
Quote:
To reduce the amount of memory required to set bits from a large DIB on a device surface, an application can band the output by repeatedly calling SetDIBitsToDevice, placing a different portion of the bitmap into the lpvBits array each time. The values of the uStartScan and cScanLines parameters identify the portion of the bitmap contained in the lpvBits array.

I think I've tried splitting the blit in several small rectangles but the only achievement was an increased CPU usage without reducing the flickering at all (the flicker pattern changed also if I remember right).
