Hey all - following on Marc's awesome Barcelona patches, here is the code to add the fam10 target to buildrom.
It works for me, but since you used the generic.mk instead of a specific one, it didn't catch that I didn't have iasl installed.
That said, it seems like it would be nicer to have a FAMILY_10 option and just take care of the three variables that change in Serengeti_cheetah.conf. That way you get 64-bit support and the iasl check for free.
If you still want to keep it separate, I'd like the name to be Serengeti_cheetah_fam_10.conf instead of cheetah_fam_10.conf, so it's easy to see what it is.
