I am not sure why the debug driver does not load. You can verify it
with the following command after installing it. Be certain that the

kextload -nt /System/Library/Extensions/IOStorageFamily.kext
I ran this and it said the kext appears to be valid. If I reboot with
the partition as the default startup system it displays an apple with
a black line above it (appearing like it is displaying text, maybe the
reason why it fails, but the box isn't big enough). If I boot with the
partition not as default then a "no entry" sign appears.
This usually means that you've tried to run with an unstripped version
of a kernel extension. All of the symbols in your KEXT have most likely
chewed up all of the kernel's memory map.
On Panther, the kernel's map was expanded quite a bit, so this limit is
harder to reach. But you should always strip KEXTs you plan to load,
especially shipping ones. Note that if you're doing two-machine
debugging, the symbols go on the debugging system, not the target
system. And if you've just embedded extra IOLogs or the like, stripping
won't affect that functionality.
HTH,
