Quite a good number of H8/300 devices are supported in the
uClinux 2.0.x and 2.4.x kernels. from the arch/h8300/config.in
I can see:

      H8/3002
      H8/3006,3007,gdb_simulator
      H8/3044,3045,3046,3047,3048,3052
      H8/3065,3066,3067,3068,3069

For sepcifics have a look at Yoshinori Sato's pages at:

Greg
