Could you try to upgrade to the 2.6.24 kernel from sid?  Basically, I
recommend you first make a backup of your flash content so you can go
back to your current kernel in case the upgrade to 2.6.24 fails.  Do:
  cat /dev/mtdblock? > backup
and save the file somewhere.

Then upgrade to 2.6.24:
  wget http://ftp.de.debian.org/debian/pool/main/l/linux-2.6/linux-image-2.6.22-3-ixp4xx_2.6.22-6_arm.deb
  sudo dpkg -i linux-image-2.6.22-3-ixp4xx_2.6.22-6_arm.deb
  reboot

Would be good to know whether you still see this problem with 2.6.24.
