 up.

 Ok, any tips on how to determine which of these problems I have?

 i386 PC386 now behaves like the rest for both Qemu variants

 Yes I should've mentioned this. Using the following 3 sets of options,
 which are more in line with what had worked previously, the tests hangs
 before the output

 qemu-system-i386 -m 128 -boot b -hda path_to/rtems-boot.img -no-reboot
 -monitor null -serial stdio -nographic -append "--console=com1;boot;"
 -kernel hello.exe

 or

 qemu-system-i386 -no-reboot -serial null -serial mon:stdio -nographic
 -kernel hello.exe
 (in this case 'kill pid' must be issued)

 or

 qemu-system-i386 -no-reboot -monitor null -serial stdio -nographic -kernel
 hello.exe

 and with a simpler set of options suggested by Sebastian it hangs after
 the output and behaves like the others as detailed above

 qemu-system-i386 -monitor null -nographic -serial stdio -nodefaults
 -kernel hello.exe
