Yes, the kernel has a scrollback buffer, which is what I wanted to know in the first place. However, you seem to be overlooking something or I'm not understanding. I'm not feeling well so it could be my fault. That is that in very old versions of Speakup from cvs, I could easily cat those same README files to the exact same synthesizer and speech would go on forever. I once let it read every single boot message from the kernel starting to the login prompt with no problem. It's only now in newer git versions that the 4 KB bug shows up, so I still consider it a bug that hasn't been fixed. I admit that I know little of handshaking and serial communication, but before there was no problem and now there is. This can be easily demonstrated with the grml 1.1rc1 live CD, which still had unlimited text output with speech not stopping. Apparently the final 1.1 release upgraded the Speakup version so probably has the bug. I don't know exactly when the bug happened but it goes back to my kernel build from the April git clone and probably before that. I don't remember if the Shane Etch CD has this or not, I would have to check.
