Fix the SPD to channel mapping. Please note that there is something wrong with UMA.

Single channel (in slot DDR1 and DDR3) produces strange artefacts on screen (and hang)
Dual Channel (in DDR1 and DDR2 aka blue slot) - works nice
All slots populated - same case as Single channel - must be something wrong with UMA.

Tested with 2x 512MB CAS 2.5 DDR400
