Any one working on a port of OWFS (One Wire File System http://owfs.org/ ). This allows Dallas/Maxim 1-Wire devices to be easily accessed. It requires FUSE and possibly USBlib (depending on the master you use.) FUSE may be already in the kernel. It runs on NSLU2 and WRTG platforms. I am particularly interested in the HA7s master. The HA7s (http://www.talk1wire.com/HA7S--ASCII-TTL-1-Wire-Host-Adapter-SIP_p_23.html) is a 6 pin device that operates at 3.3v or 5V (VCC,GND,TX,RX,OWGND,OWDATA) nearly perfect for the 2440!!! and inexpensive!!
