    I know nothing about GCC's interrupt attributes,
    however, there is no problem writing ISR's  from scratch (no OS)
    for the ppc. There are several boot loaders, monitors etc. out there
with examples.
     There is even one inside the Linux Kernel source - though it i
probably far more complex than you need.

    Somewhere I have something for the ppc405 I can send you - but most
ppc's are similar.
