great!

Can't SPD data just be used to do that? 

Size and type detection definitely wont work without SPD-ROMs for SDRAM
and all kinds of DDR.

On DDR we use SPD for everything. Why do you say it should not be used
for sizes ?

First thought: No. 

Second thought: If it does not waste the algorithms and keeps them
readable. Why not..

Sure. When you have something working, send it to the mailing list. No
code gets into the repository without being reviewed first, so there is
plenty of opportunity for discussion
