So have the automated script also document what the options are so that you can quickly check what is and isnt' enabled by comparing the version number with the timestamp to the document.

I don't think it'll happen again.
The previous versions of my kernel were all "NewzImage.tns" and with that version I switched over to "zImage.tns"
but forgot to change the bootscripts.

So, now even midori is working:


LxPanel:


PcManFM:


What's next? ;D
LxPanel and PcManFM are running pretty smoothly, but midori is not really usable. But it knows CSS, which links doesn't.

Wow. Never expected to see a full-featured webkit browser running on there.

Is this only a GUI browser or also linux with GUI (judging from the last screen I guess it is?)

This is a full-on X.org window system. We could run lxde at this point if we wanted to, but it would be slow....(lxde panel is running now)

Actually, lxpanel is running quite fast.
If we don't use lxdm (lxde window manager), the only problem will be the screen, as it's very small.

I guess it would be doable wouldn't it? They do exist: http://www.displaylink.com/shop/monitors
and http://www.trustedreviews.com/aoc-e2251fwu-22in-usb-monitor_Monitor_review
Imagine your nspire with 22" full HD screen :P

Is there any chance that it will support USB 2.0?

Somewhere I read it hasn't even got an USB 2.0 controller.
But why is it an EHCI then? That doesn't make any sense..
I hope it's a real EHCI, the whole thing would run much faster.

It had better be USB 2.0, since OTG mode (where you can be either a host or a slave) wasn't introduced as a specification for 1.1.

No display (all output is through serial at the moment) or USB support yet though. Will come soon! Aside from that, I will need lots of testing.

On the CX port, I also need to merge vloginator's patches for the LCD (I will do it together with the Clickpad/Touchpad display support).
