This patch set does work better than the first one. Debian Linux, Darwin, and Mac OS 10.4 all boot with your patches. The only one to that did not work is Mac OS 9.2. Even when I add the '\r' to '\n' patch, it still doesn't boot. It could be a problem on my end. Or it could be you are on to something...
