It's already there in the shamcop_nand driver in the kernel sources
(http://cvs.handhelds.org/cgi-bin/viewcvs.cgi/linux/kernel26/arch/arm/common/ipaq/shamcop_nand.c).
Read works great, but we didn't dare yet to play with write. The risk is
to damage the HTC bootloader and get a brick.

Work is on going by Joshua. You can try to boot LAB from HaRET to
validate it (no risk).

More things that are missing or are not complete yet:

    * Touchscreen calibration: that's why I'm working on OpenEmbedded,
      which should handle calibration data in a correct way (through the
      Xserver or Opie), without having to write an extra ts driver as
      h3600_ts.
    * Bluetooth
    * SD: it would be great if we could get the latest SAMCOP patches
      from Pierre Tardy, once he manages to convince his boss (with the
      GPL, you have to share code changes only when you make releases)
    * DMA: same issue. Pierre also implemented patches.
    * 1 wire interface, to get battery information. This would replace
      the obsolete /proc/hal/battery file.
    * Then, power management, suspend, resume, alarm wake-up...
    * Sound recording: not tested yet.

You're right not to be afraid of Kernel hacking. At least, it's fairly
easy to write modules.

Thanks for offering your help! You can chose what you're most interested
in. You can also work on user applications, for example by creating a
command line ogg player package with OpenEmbedded.

Don't hesitate to share more questions with the list.
