Well, since as is friendly enough to tell you the line number, why
don't you take a look at what's there?  In 2.1, it looked something
like:

/*
 * btext: beginning of text section.
 * Also the entry point (jumped to directly from the boot blocks).
 */
NON_GPROF_ENTRY(btext)
	movw	$0x1234,0x472			/* warm boot */

	/* Set up a real frame, some day we will be doing returns */
	pushl	%ebp
	movl	%esp, %ebp


I'd guess that your locore.s is hosed, and that you'll see a lot of
junk starting on line 156.
