Both 0.3.0 and the latest head revision refused to build until I made this patch. Am I misunderstanding something?

On another track, I suspect that there may be a typographically generated bug in cpu/i386/start16.S. The code reads like this.
/* Turn of cache (this might require a 486-class CPU) */ movl %cr0, %eax orl $060000000,%eax movl %eax, %cr0 wbinvd
I believe that the correct immediate value is $0x60000000. The given octal value is 0x00c00000 hexadecimal. According to the Intel documentation I have on hand, these bits are presently reserved in %cr0.
