On a *GB card, I used 2GB per distro, and leftovers for init, swap and media-
things/backup:

root at tp:/home/wbk/embedded# fdisk -l /dev/sdb

Disk /dev/sdb: 8270 MB, 8270118912 bytes
255 heads, 62 sectors/track, 1021 cylinders, total 16152576 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *         128      131071       65472    c  W95 FAT32 (LBA)
/dev/sdb2          131072     4325375     2097152   83  Linux
/dev/sdb3         4325376     8519679     2097152   83  Linux
/dev/sdb4         8519680    16152575     3816448    5  Extended
/dev/sdb5         8521728    12716031     2097152   83  Linux
/dev/sdb6        12718080    13766655      524288   82  Linux swap / Solaris
/dev/sdb7        13768704    16152575     1191936    b  W95 FAT32

I think 2GB is much more than needed. Most space is needed, as said before, 
for media files, map images and backup/"non-volatile" (that in my case is just 
over 1GB). I have not tried yet if it _needs_ to be FAT for QtMoko in order to 
be able to build a database on it. I'd prefer an FS that supports more 
features.

Best regards,
