Yes it is. For IA-32, have a look the code in
kernel/src/glue/v4-ia32/exception.cc, specifically at the
send_exception_ipc() routine.

I think it's just a matter of implementing exc_catch() properly; apparently
just nobody has yet required that for some types of exceptions. So it's
"planned" in the sense that somebody will fix it eventually :)

I wouldn't say that you'd have to stop all further planning. IA32 #GP's, for
instance, are implemented; if you just want to test how exception handling
works, raise such exceptions and everything will be "fine". Also, as I said,
my guess is that implementing the other cases shouldn't be rocket science as
well.
