That works.  Another solution would be to add a line:

in: ${BP}/dev/mmc/sdhci/build/sdhci.fc

to force that module to be built.

Still another solution would be to comment out line 105 entirely.

Well, I wouldn't call 4 lines a "lot" of changes in resetend.fth, but be 
that as it may ...

The most likely cause of the problem is the changed value of gdt-pa in 
cpu/x86/pc/virtaddr.fth

I changed that to avoid some data structure that some BIOS was using - 
but maybe the new place is causing a conflict with something else.  You 
could try changing it back to 1040 to see what happens.
