Note on porting the SDMergE400 mod for stock 2.3.6 firmware,
First, I de-odexed the ROM with dsixda's kitchen, also added root. Then I fixed stock init.rc as follows:
on early-init
start ueventd
on init

and re-packed the kernel. Also I changed the /system/etc/format-fat32.sh that forcedly restored vfat partition on new data partition:
#!/system/bin/sh
exit 0
and packed a flashable zip with a custom-fixed updater-script. I had to use convert update-script feature from kitchen, but finally this approach had missed several critical symlinks, so I mounted the system.img in my linux box and got the list of necessary symlinks pretty-printed for edify scripting:
find . -type l | while read LINE;
do
symstr=`ls -la $LINE`
echo 'symlink("'`echo $symstr | awk '{print $11}' | sed 's/^\./\/system/'`'","'`echo $symstr | awk '{print $9}' | sed 's/^\./\/system/'`'");' >> /tmp/kernels/stock_e400/stock_e400_symlinks
done
Finally I zipaligned and created a zip archive and tried to flash. Nothing! So I had to take zip from CyanogenMod and replace system folder with mine and the updater-script with new one. That worked.
The phone booted, but it still misses a /mnt/extra-sd so I need to patch storage_info.xml too.
UPDATE: there is no storage.info in Gingerbread (only ICS+) and I got a damaged card issue. So I digged inside and found that mmcblk0p20 value is hardcoded (sic!) into vold, framework, camera, browser etc!
UPDATE: The LG's tivoized vold forces /dev/block/vold/179:20 (0xb314) for /mnt/sdcard and /dev/block/vold/179:32 for /mnt/sdcard/_ExternalSD. External SD entry is controlled by vold.fstab, and /mnt/sdcard by code inside vold to prevent end-users from modding.
I had to patch vold to alter 0xb314 partNode with 0xb320 and used stock vold.fstab. As a result, the external SD card was mounted twice - as primary and secondary cards. To prevent the second mountpoint to process, I trued to delete the ExternalSD entry, but that caused vold to lose partition at all. The obvious solution was the following vold.fstab:

Here we have an ExternalSD entry but its name is not ExternalSD, so vold drops a framework request but handles the partition internally on 'volume mount /mnt/sdcard' call to vold.
Now the external card is reported as absent and the primary card has the size and feel of external one. The USB storage also works at full-speed (~4MB/sec) so this task can be considered as done
