cannot read DS2760 Battery chip on h5555: cannot enter learn mode

Hello

I just bought a ipaq h5555 and flashed ROM to run familiar. I cannot get
battery status, and I cannot enter learnong mode.

cat /proc/hal/battery
AC status : 1 (online) <= ok, changes when I unplug pda
Battery #0
  Chemistry :0xff (unknown) <= Li-polymer written on the battery pack
  status :0x08 (charging) <= ok; becomes 0x01 when AC unplugged
  voltage :0x030f (3823 mV) <= doesn't decrease when running a
few hours unplugged
  percentage :0x00 (0%) <= I've never seen any other value
 Life (min) : 0

My battery is a replacement battery pack for 54xx/55xx (1400mAh). I'm
not sure it is an authentic HP battery. I wonder if DS2760 is present in
the battery.

Because voltage never decreases, I cannot enter learn mode. As long I
plug AC power, the battery LED flash, and load the battery. I thing it
may be damaged when charging if it is already full.

I'm wating for a new 3000 mAh battery pack. I'll test it with above
commands.

I got an other question about filesystems in familiar.

I see that /home/root is in the jffs2 filesystem (mounted /) . Is it
safe to write data on flash memory ? Why not use a SD card or RAM to
store PIM data and user files ?
