Here's some more from the wiki (per this discussion http://talk.maemo.org/showthread.php?t=62826&page=2):

- DO THIS FIRST:

Step 1: Partitioning

To be able to install the "sudo gainroot" command you need to install a package called rootsh from the application manager first!

1. Open up the xTerm and become root with this command:

sudo gainroot

2. First un mount the microsd card

umount /dev/mmcblk1p1

3. For this step you need to know the capacity of your memory card. The Android partition can only be 2GB, so you need to create a FAT partition that is so large there will only be 2GB left. The number must be in MB, example some recommended sizes are 1, 100, 2100, 6100, 14100, 30100. If its 8GB you can choose a number like 6100MB, if its 4GB you can choose a number like 2100MB. If your memory card is 2GB or below, you can choose 1MB as a number If you do not do this correctly you will not be able to use Android Market!

sfdisk -uM /dev/mmcblk1 << EOF

,<YOUR NUMBER IN MB>,C
,,L
,,
,,
EOF

for a 8GB card:

sfdisk -uM /dev/mmcblk1 << EOF
,6100,C
,,L
,,
,,
EOF


4. Unmount microsd again as maemo sometimes tried to mount

umount /dev/mmcblk1p1

5. The actual formating!

mkdosfs /dev/mmcblk1p1
mke2fs -L NITDroid -j -m0 /dev/mmcblk1p2

- THEN USE THE AUTOINSTALLER
