Is CR4 some new fancy register?

Anyway you're right about my configuration. Now I've recompiled
pistachio, with CONFIG_CPU_IA32_I586. But that doesn't help much (it
crashes before it gets to the kernel). Do I have to give any special
flags to gcc when compiling laden and friends?

I'm using gcc-3.3.2, configured and built on a K7 with no special
options. I'm getting confused, I thought gcc on x86 by default
generated only code that is valid on all variants from 386 and up.
