I would guess that it is an artifact of not having HC 1.2.5 as the info I got
from Apple SPECIFICALLY says:

	A) Do NOT run HC versions before 1.2.5 on system 6.0.4
	B) Do NOT run HC 1.2.5 on systems before 6.0.4

I think you need to upgrade your HC.  I have a RasterOps 264 board and have
had no problems with HC 1.2.5 and sys 6.0.4 at any bit depth.
