The problem here is that you appear to be massively underestimating the 
amount of work that would be required to actually support this 
configuration. We'd need to audit every ioctl entry point, every file in 
proc and every sysfs attribute. We'd need to port every application that 
uses vm86 over to using x86emu. We'd need to add, test and support a 
32-to-64 bit cross building toolchain. yum would need some amount of 
work that Seth has implied is significant. That's a lot of work for 
marginal benefits, and nobody seems interested in stepping up to do that
