As the one who is championing adaptive modules in a new and improved Linux kernel, I can tell you that I really like this hardware screen/braille approach. I'd not heard of it before. I'm not going to go that route, most people won't, but it definitely has some miles left in it. Let me tell you a brief story. We just got a new box with an rtl8193 ethernet card in it. Works fine on Windows, but I want a dual boot machine. I bring up Linux and it can't assign an irq to the card. It says that it simply can't. It says I have to change something in bios. Full instructions are available on the web. http://www.scyld.com/expert/irq-conflict.html But there are no adapters for bios. I have to find a sighted friend to hit f1 at the right time and go into bios and make the changes. Speakup won't help - jupiter (my own adapter) won't help - brltty won't help - and so on. The only solution that provides this level of independence is the video hardware approach, and today, I wish I had it. But most people aren't going to mess with their computer's internals, so I'm sure OS-resident adapters will continue to rule. Karl
