Re: NetBSD/i386 7.0 hangs booting 486

Was this a regression from the problems that I had in February? Or did 
gcc/llvm make changes to their code that assume CPUID exists 
unconditionally? I seem to recall the problem last time was i386-specific 
code in the NetBSD source tree proper unconditionally trying to call CPUID. 
I should've been updating my kernel more frequently :/, but alas my time 
management isn't great.

LLVM doesn't support anything lower than the Pentium, so I'm unsure if 
they'll accept the patch :(.

Great, I've committed to head and will ask for -7 pullups. I will
submit them to the gcc and llvm people later.

Thanks for testing!
