That's exactly part of the reason why this code is moved -- it isn't needed
for 32-bit cards, and 32-bit cards should be able to be run with no 16-bit
support built into the kernel

exactly this, even though some parts might not be able to be modularized --
so think of them as booleans...

not it alone, but yes...

cs and friends: core [32 and 16 bit]
ds and friends: 16-bit
cardbus (and friends?): 32-bit
