Hi,
 
     I have used vfat for first partition and ext3 for the second 
partition.

     This is the procedure i have followed for installing qtopia on sdcard.
     
     My  Host PC has  FC 9.

     1) connected to Neo freerunner by SSH

     2) Partitioned SD card  :
         fdisk /dev/mmcblk0    

     created a 8 mb partition for  kernel and another one for the rootfs 
which took up
     all the remaining space
 

  Command (m for help): d
  Selected partition 1
  Command (m for help): n
  Command action
     e   extended
     p   primary partition (1-4)
  p
  Partition number (1-4): 1
  First cylinder (1-983, default 1):
  Using default value 1
  Last cylinder or +size or +sizeM or +sizeK (1-983, default 983): +8M
  Command (m for help): n
  Command action
     e   extended
     p   primary partition (1-4)
  p
  Partition number (1-4): 2
  First cylinder (18-983, default 18):
  Using default value 18
  Last cylinder or +size or +sizeM or +sizeK (18-983, default 983):
  Using default value 983
  Command (m for help): w
  The partition table has been altered!
  Calling ioctl() to re-read partition table.

  fdisk: WARNING: rereading partition table failed, kernel still uses old table:   Device or resource busy 

3)    Got an  fdisk warning so  umounted  :
      
        umount /dev/mmcblk0p1 

       redone the step2 again.No error second time.

4)Formatted the SDcard :
     
     for first partition.

    a) mkfs.vfat /dev/mmcblk0p1

     for second partition.
 
    b)mkfs.ext3 /dev/mmcblk0p2

5)Mounted the sdcard:

  mount /dev/mmcblk0p1 /media/card
  mkdir /media/card/boot

  mkdir /media/mmcblk0p2
  mount /dev/mmcblk0p2 /media/mmcblk0p2

6)unpacked qtopia:

   got this two files :

   1. uImage-2.6.24+git18+9c058ff0d2641df3c36fc3300acb72078d2c41d4-r0-om-gta02.bin

   2. qtopia-4.3.2-gta02-rootfs-07172049.jffs2

 7)Mounted the rootfs on loopback device:

   export loop=$(losetup -f)
   losetup $loop <rootfs.jffs2>
   modprobe block2mtd block2mtd=$loop,131072
   modprobe jffs2
   modprobe mtdblock
   mkdir   mntpnt                                   
   mount -t jffs2 -o ro /dev/mtdblock0   mntpnt  


8)created compressed tarball.

     tar czf qtopia-4.3.2-gta02-rootfs-07172049.tar.gz -c mntpnt

9)Transfer this compressed tarball to the second partition of the 
MicroSD that is mounted
    on the FreeRunner:

   scp qtopia-4.3.2-gta02-rootfs-07172049.tar.gz 
root at 192.168.0.202:/media/mmcblk0p2/

10)Unpack the rootfilesystem:

      cd /media/mmcblk0p2
      tar xzf qtopia-4.3.2-gta02-rootfs-07172049.tar.gz rm    
      qtopia-4.3.2-gta02-rootfs-07172049.tar.gz
      rm -f /media/mmcblk0p2/boot/*

11) Installed kernel.

mv 
uImage-2.6.24+git18+9c058ff0d2641df3c36fc3300acb72078d2c41d4-r0-om-gta02.bin 
     uImage.bin
scp uImage.bin root at 192.168.0.202:/media/card/boot/

 scp uImage.bin root at 192.168.0.202:/media/card/

12)shutdown and boot in qtopia.

    Booted from Sdcard

Now when kernel is booting .It's giving  kernel panic.
