Nope, its not ;/

Im on a Intel Pentium 200Mhz PC, 64MB RAM,

ld -m elf_i386 -T /usr/src/linux/arch/i386/vmlinux.lds -e stext

init/main.o: In function `check_fpu':
init/main.o(.text.init+0x53): undefined reference to `__buggy_fxsr_alignment'
make: *** [vmlinux] Error 1

same fatal error. Where is this function defined in the i386 asm header?

If so, I could fix this and submit a patch.

[root@coredump linux]# grep -r "__buggy_fxsr_alignment" *
include/asm-i386/bugs.h:  extern void __buggy_fxsr_alignment(void);
include/asm-i386/bugs.h:  __buggy_fxsr_alignment();
include/asm/bugs.h:  extern void __buggy_fxsr_alignment(void);
include/asm/bugs.h:  __buggy_fxsr_alignment();

/* Enable FXSR and company _before_ testing for FP problems. */
        /*
         * Verify that the FXSAVE/FXRSTOR data will be 16-byte aligned.
         */
        if (offsetof(struct task_struct, thread.i387.fxsave) & 15) {
                extern void __buggy_fxsr_alignment(void);
                __buggy_fxsr_alignment();

Where is this function? Where is it defined? When i grep the whole dir i dont see
this function anywhere?
