Done. Looks good.
(I did _not_ do a full rebuild and installation, only a build test.
I will do a full blown test with 2.6.24.3.)

Note: Your original did not fully apply, I think it had lines like
-$(obj)/cuboot-taishan.o: BOOTCFLAGS += -mcpu=440
-$(obj)/cuboot-katmai.o: BOOTCFLAGS += -mcpu=440
which I did not have in my 2.6.24.
Probably because you've used a git version of linux.
What I did was to change the similiar occurances from 440 to 405.
