Having got some free time (it doesn't happen often), I've been playing with the
"ts-virtual-dev" development environment.
I thought I'd try and get kernel 2.6.34 working on the ts-7300.
I got the kernel, applied Matt's patches and built on the .config from 2.6.29.
I had to add a line to the watchdog driver to turn the timer off, otherwise the
board would keep rebooting.
I now get to the fast boot prompt.
unfortunately, I can't get the sd card driver to load.
insmod: cannot insert 'ts72xx_sdcard.ko': No such device (-1): No such device
Anyone got any ideas? I noticed that the device name is now "tssd" rather than
"tssdcard" in the code.

Here's the kernel print out...
