Very small X for embedded systems

Hello Group,

I'm searching for a simple way to get some rough graficfunctions on a small 128x64 pixels display, but I have no
working results by now.
I know the GPE-Project via openzaurs.org. I own a Zaurus SL5500G and it is really similar to what we are building,
except the display is much smaller.

To give you a rough overview about my target system:
- Atmel AT9RM9200, ARM9-based system-on-a-chip
- 16 MB Flashrom, jffs-filesystem
- 32 MB SDRAM
- 4x UART, USB-host and -gadget, ethernet, aso.
- 128x64x1 lc-display, framebuffer-device
- linux-kernel 2.6.15
- glibc 2.3.4

By now we use only a linux framebuffer console and ncurses for our user-interfaces, but we want to use some gafics.
I tried to build a tiny-x/kdrive server for the target and it works, but with all the needed stuff it gets up to 5 mb
to run e.g. xclock.
Now I have to shrink it down to about 1mb, but I have no ideas how to do that.  There are functions we do not need,
like antialiasing or font randering.

Can you give me some hints to do that?

Thanks and greetings,
Jonatan Antoni
