oops, sorry, you are right...

yeah, that's what i thought, too. but if you're able to read the values 
from the spd it should be no problem setting them!?

hmm, no. actually x86_enable_cache() just emits a post code, prints some 
info and calls enable_cache() which is an inline in cache.h which just 
enables L1 cache by flipping a bit in the processor configuration 
register 0 (CR0). that's all.
it should be renamed to enable_L1_cache() to avoid confusion.
the L2 cache can not be enabled in CR0. just take a look at the code and 
you'll see.
