I've actually compiled up a kernel more recently than that to check it
still built ok, but haven't done anything much with the E3 recently.

No. I did wonder if boosting the speed to 230.4k rather than just 115.2k

I had this hooked up to the OMAP gpio switch framework, but I found it
conflicted with the FIQ keyboard patch and caused crashes. Possibly the
gpio-keys driver is the way to do this these days?

If you limit Google to the list archives you should have more luck.

I didn't really investigate it. 2.4 doesn't interest me.

Yes, you can dump the contents but I don't recall anything of real
Do you believe in happy endings?
