Yes, however most of the subsets you mention aren't implemented.
Specifically only the ARM VFP coprocessor can be easily disabled.

Restricting emulation to i586/armv4 isn't particularly hard, it just needs 
some time spent to do the work. The new features I'm adding (eg. armv6) are 
going to be optional from the start.

I have no personal plans to do x86 or armv4. People periodically request this, 
but so far noone has cared enough to invest the necessary effort.

uClinux runs fine under qemu. Just because the CPU has an MMU doesn't mean you 
have to enable it.
