Check out HARET : http://www.handhelds.org/moin/moin.cgi/HaRET
It will let you boot Linux from CE. Its more of a temporary solution
to play around with it.
I haven't used this myself but I've heard good things about it.

Alternatively If you have access to the microsoft boot loader (called
eboot) and a network connection (the way you normally upload CE images
during dev) I have written a couple of python scripts that:
1) convert a standard linux zImage into something eboot can understand
2) upload to the device over the network (basically glorified TFTP) from linux.

They're not online at the moment but I could make them available if
anyone is interested.

You'll need two things:
1) A working kernel framebuffer driver for your hardware (you don't
say what it is) Do you know the actual chip? (ARM 926EJ-S is just the
CPU core). Usually such devices use a SoC containing an arm core and
common peripherials (display controller, USB, ...) such as i.MX21,
iMX27, PXA..
2) Touchscreen support

Once that's available emdebian has GPE (a stripped down gnome) :
