It still works ... it just isn't complete as most of the syscalls
added in the past 18 months haven't been included.

I've no idea. Two OSDs have been shipping the Intel s/w emulator for
a while now, one installs it by default. So the number of users is
probably diminishing. When people upgrade to Montecito, s/w emulation
is the only option, which will further reduce the user population.

The kernel doesn't handle BIOS code execution ... so the value of
CONFIG_IA32_SUPPORT makes no difference to this.
