The memory detection routine hangs right after spd detection 
indefinitely, which it gets wrong. With memdetect off I can boot 
into the system fine. 
The point where it hangs is in scan_mem() right after the call to 
scan_dram_controller, so the culprits are one of these two

scan_memory(&Platform); // unfortunately still necesary for some 
comp where spd cant read correct speed
scan_spd(&Platform);

Unfortunately none have any usable logging so I can't figure out 
which one is the culprit.

I have an Acer Travelmate 5720, with DSDT fixes applied
