xen/include/asm-i386/apic.h for one... and there are more dangerous 
looking things:
xen/include/asm-i386/dma.h includes both "linux/config.h" and 
"linux/spinklock.h".  This is very likely to be built into the drivers, 
and likely to cause major havoc if you change the cacheline size.

Only arch/i386/Rules.mk specifies -nostdinc.  This is really dangerous 
if you are not building on a 2.4.24 or very close kernel, and makes 
cross-compiling out of the question.
I should have a patch for a slightly cleaner build today that you could 
try out.  It's likely to be largish, since I may need to pull in some 
additional headers from 2.4.24.
